## Thoughts
To understand the biological system, I'll first observe the system's default behavior. The model contains four species with different initial concentrations:
- id_lphe: Initial concentration = 1
- id_e7i0: Initial concentration = 3
- id_lrve: Initial concentration = 1
- id_eqa0: Initial concentration = 1

I'll request an observation experiment to see how these species change over time and get baseline data.

# Iteration 1
## Thoughts
Analyzing the experimental data reveals some interesting dynamics:

1. Species Behavior:
- id_lphe: Increases from 1.0 to around 2.49 over time
- id_e7i0: Decreases from 3.0 to around 0.251
- id_lrve: Increases from 1.0 to around 0.679
- id_eqa0: Decreases from 1.0 to around 0.951

2. Observations:
- There seems to be an inverse relationship between id_lphe and id_e7i0
- id_lrve shows a gradual increase
- id_eqa0 shows a gradual decrease

These observations suggest potential missing reactions, possibly involving:
- Conversion of id_e7i0 to id_lphe
- Production of id_lrve
- Consumption of id_eqa0

I'll design an experiment to perturb the initial concentrations to better understand the system's dynamics.

# Iteration 2
## Thoughts
Comparing the two experiments reveals consistent system behavior:

1. Comparative Analysis:
- Reducing initial concentrations of id_lphe and id_e7i0 did not fundamentally change the system's dynamics
- The overall trajectory remains similar to the first experiment
- Final concentrations are nearly identical to the first experiment

2. Key Observations:
- id_lphe still increases from initial concentration to around 2.5
- id_e7i0 continues to decrease from initial concentration to around 0.25
- id_lrve increases from 1.0 to about 0.68
- id_eqa0 decreases from 1.0 to about 0.95

3. Hypothesis:
There might be a conversion reaction between id_e7i0 and id_lphe, and possibly a consumption/production mechanism for id_lrve and id_eqa0.

I'll design an experiment to further probe the system by significantly changing the initial concentrations of id_lrve and id_eqa0.

# Iteration 3
## Thoughts
Analyzing the third experiment reveals fascinating insights:

1. Consistent System Dynamics:
- Despite significantly reducing initial concentrations of id_lrve and id_eqa0, the system's overall behavior remains remarkably stable
- Final concentrations are almost identical to previous experiments
- Suggests robust, potentially interconnected reactions between species

2. Detailed Observations:
- id_lphe: Increases from 0.14 to 2.49
- id_e7i0: Decreases from 3.0 to 0.251
- id_lrve: Increases from 0.1 to 0.677
- id_eqa0: Increases from 0.5 to 0.95

3. Emerging Hypotheses:
- There seems to be a conservation mechanism that normalizes species concentrations
- Potential reactions might include:
  a) Conversion of id_e7i0 to id_lphe
  b) Production of id_lrve independent of its initial concentration
  c) Slight consumption/production of id_eqa0

To further investigate, I'll design an experiment that changes multiple species simultaneously to probe potential interaction mechanisms.

# Iteration 4
## Thoughts
The latest experiment provides crucial insights into the system's behavior:

1. Robust Homeostatic Mechanism:
- Despite significant variations in initial concentrations, the system converges to nearly identical final states
- Final concentrations are remarkably consistent across all experiments
- Suggests strong regulatory mechanisms or interconnected reactions

2. Detailed Observations:
- id_lphe: Increases from 0.2 to 2.50 (consistent with previous experiments)
- id_e7i0: Decreases from 1.0 to 0.252 (consistent pattern)
- id_lrve: Increases from 0.5 to 0.684 (slight variation, but similar trajectory)
- id_eqa0: Increases from 0.2 to 0.952 (consistent trend)

3. Emerging Hypotheses:
- There appears to be a conversion reaction from id_e7i0 to id_lphe
- id_lrve seems to have a production mechanism independent of its initial concentration
- id_eqa0 shows a slight consumption trend

To further investigate the potential interactions, I'll analyze the experimental data statistically and design a targeted experiment.

## Action

### Code
```python
import numpy as np
import pandas as pd

# Analyze concentration changes across experiments
experiments = ['iteration_0', 'iteration_1', 'iteration_2', 'iteration_3']
species = ['id_lphe', 'id_e7i0', 'id_lrve', 'id_eqa0']

def analyze_concentration_changes(experiments, species):
    changes = {}
    for species_id in species:
        initial_concentrations = []
        final_concentrations = []
        
        for exp in experiments:
            df = experiment_history[exp]
            initial_concentrations.append(df.loc[df.index[0], species_id])
            final_concentrations.append(df.loc[df.index[-1], species_id])
        
        changes[species_id] = {
            'initial_mean': np.mean(initial_concentrations),
            'initial_std': np.std(initial_concentrations),
            'final_mean': np.mean(final_concentrations),
            'final_std': np.std(final_concentrations)
        }
    
    return changes

concentration_analysis = analyze_concentration_changes(experiments, species)
print("Concentration Change Analysis:")
for species, stats in concentration_analysis.items():
    print(f"{species}:")
    for key, value in stats.items():
        print(f"  {key}: {value}")
```

        "id_lphe": 0.1,   // Minimal initial concentration

# Iteration 5
## Thoughts
The statistical analysis reveals critical insights into the system's behavior:

1. Concentration Dynamics:
- id_lphe: 
  * Initial mean: 0.675
  * Final mean: 2.494
  * Consistently increases regardless of initial concentration
- id_e7i0:
  * Initial mean: 2.25
  * Final mean: 0.252
  * Consistently decreases with high predictability
- id_lrve:
  * Initial mean: 0.65
  * Final mean: 0.680
  * Minimal variation in final concentration
- id_eqa0:
  * Initial mean: 0.675
  * Final mean: 0.951
  * Slight increase with low variability

2. Key Observations:
- Extremely low standard deviations in final concentrations suggest a robust, regulated system
- Strong indication of interconnected reactions with homeostatic properties
- Potential conversion reaction from id_e7i0 to id_lphe
- Possible production mechanism for id_lrve independent of initial conditions

3. Hypothesis:
There might be a core reaction network with:
- A conversion reaction from id_e7i0 to id_lphe
- A production mechanism for id_lrve
- A slight consumption mechanism for id_eqa0

I'll design an experiment to test the conversion hypothesis by creating an extreme initial condition.

## Action

### Code
```python
import libsbml

# Prepare to add a reaction based on our hypothesis
reader = libsbml.SBMLReader()
document = reader.readSBMLFromString(input_sbml_string)
model = document.getModel()

# Add a reaction from id_e7i0 to id_lphe
reaction = model.createReaction()
reaction.setId("e7i0_to_lphe_conversion")
reaction.setReversible(False)

# Reactant
reactant = reaction.createReactant()
reactant.setSpecies("id_e7i0")
reactant.setStoichiometry(1.0)
reactant.setConstant(False)

# Product
product = reaction.createProduct()
product.setSpecies("id_lphe")
product.setStoichiometry(1.0)
product.setConstant(False)

# Kinetic law (simple mass action)
kinetic_law = reaction.createKineticLaw()
math = libsbml.parseL3Formula("k * id_e7i0")
kinetic_law.setMath(math)

# Parameter
parameter = model.createParameter()
parameter.setId("k")
parameter.setValue(0.1)
parameter.setConstant(True)

# Write updated SBML
writer = libsbml.SBMLWriter()
hypothesis_sbml = writer.writeSBMLToString(document)

# Simulate to verify

# Iteration 6
## Thoughts
The latest experiment and hypothesis simulation provide crucial insights:

1. Experimental Observations:
- With extremely high initial id_e7i0 (10.0) and low initial id_lphe (0.05):
  * id_lphe increases from 0.05 to 2.34
  * id_e7i0 decreases from 10.0 to 0.248
  * Consistent with previous experiments' pattern

2. Hypothesis Simulation Analysis:
- The simple mass-action conversion reaction partially captures the system's behavior
- Simulated model shows similar trends of id_e7i0 decreasing and id_lphe increasing
- However, the experimental data shows more nuanced dynamics

3. Key Insights:
- Conversion from id_e7i0 to id_lphe appears to be non-linear
- The conversion rate is not constant and seems to depend on concentrations
- Other species (id_lrve and id_eqa0) maintain their characteristic behaviors

4. Refined Hypothesis:
- The conversion might be a Michaelis-Menten-like kinetics
- Possible additional regulatory mechanisms influencing the conversion
- Need to explore more complex kinetic representations

## Action

### Code
```python
import libsbml
import numpy as np

# Create a more complex kinetic representation
reader = libsbml.SBMLReader()
document = reader.readSBMLFromString(input_sbml_string)

reaction.setId("e7i0_to_lphe_conversion")
reaction.setReversible(False)

# Reactant

reactant.setConstant(False)

# Product

math = libsbml.parseL3Formula("(Vmax * id_e7i0) / (Km + id_e7i0)")
kinetic_law.setMath(math)

# Parameters

Vmax.setValue(0.5)
Vmax.setConstant(True)

# Iteration 7
## Thoughts
Comparing the experimental data with the Michaelis-Menten hypothesis reveals critical insights:

1. Experimental Observations:
- With initial id_e7i0 at 5.0 and id_lphe at 0.1:
  * id_lphe increases from 0.1 to 2.46
  * id_e7i0 decreases from 5.0 to 0.25
  * Consistent with previous experiments' pattern

2. Hypothesis Simulation Limitations:
- The Michaelis-Menten model shows similar overall trends
- However, the simulated model:
  * Reaches final concentrations too quickly
  * Does not capture the nuanced, gradual changes observed experimentally
  * Suggests more complex regulatory mechanisms are at play

3. Emerging Hypotheses:
- The conversion process likely involves multiple steps or regulatory factors
- Possible additional interactions between species
- Potential feedback loops or inhibition mechanisms

4. Key Observations:
- id_lrve continues to show gradual increase (0.1 to 0.665)
- id_eqa0 shows consistent slight decrease (1.0 to 0.947)
- The system maintains remarkable homeostatic properties

# Iteration 8
## Thoughts
The detailed species analysis reveals profound insights into the system's behavior:

1. Concentration Dynamics:
- id_lphe:
  * Initial mean: 0.421 (high variability)
  * Final mean: 2.465 (extremely consistent)
  * Always converges to ~2.5 regardless of initial conditions
- id_e7i0:
  * Initial mean: 4.0 (high variability)
  * Final mean: 0.251 (extremely consistent)
  * Always decreases to ~0.25
- id_lrve:
  * Initial mean: 0.8 (moderate variability)
  * Final mean: 0.666 (low variability)
- id_eqa0:
  * Initial mean: 0.814 (moderate variability)
  * Final mean: 0.948 (very low variability)

2. Key Observations:
- Remarkable homeostatic mechanism across all species
- Suggests complex, interconnected regulatory network
- Potential multi-step conversion processes
- Possible feedback loops or saturation kinetics

3. Emerging Hypotheses:
- Conversion from id_e7i0 to id_lphe involves multiple steps
- id_lrve has a production mechanism independent of initial concentration
- id_eqa0 undergoes slight consumption
- System likely has multiple regulatory mechanisms ensuring stable final states

# Iteration 9
## Thoughts
The latest experiment and hypothesis simulation provide crucial insights:

1. Experimental Observations:
- With very low initial concentrations of id_e7i0 (0.5) and id_lphe (0.05):
  * id_lphe increases from 0.05 to 2.49
  * id_e7i0 decreases from 0.5 to 0.252
  * Consistent with previous experiments' pattern

2. Hypothesis Simulation Analysis:
- Two-step conversion model with Hill-like regulation shows:
  * More complex dynamics compared to previous simple models
  * Introduction of an intermediate species
  * Captures some nuanced behavior of the system
  * However, still does not perfectly match experimental data

3. Key Observations:
- Persistent system characteristics:
  * id_lphe converges to ~2.5
  * id_e7i0 converges to ~0.25
  * id_lrve increases from 1.0 to ~0.68
  * id_eqa0 decreases from 1.0 to ~0.95

4. Emerging Hypotheses:
- The system likely involves:
  * Multiple interconnected reactions
  * Complex regulatory mechanisms
  * Possible feedback loops
  * Non-linear kinetics

5. Remaining Questions:
- What drives the consistent convergence?
- What are the precise mechanisms governing species interactions?
- Are there hidden regulatory processes?

# Iteration 10
## Thoughts
The rate of change analysis reveals profound insights into the system's dynamics:

1. Concentration Change Characteristics:
- id_lphe:
  * Initial Rate: -0.337 (sharp decrease)
  * Final Rate: 0.004 (near-zero)
  * Suggests a rapid initial redistribution followed by stabilization
- id_e7i0:
  * Initial Rate: -0.159 (consistent decrease)
  * Final Rate: -0.00007 (near-zero)
  * Indicates a controlled, predictable consumption
- id_lrve:
  * Initial Rate: -0.307 (sharp initial change)
  * Final Rate: 0.001 (near-zero)
  * Implies a complex production/consumption mechanism
- id_eqa0:
  * Initial Rate: -0.006 (minimal change)
  * Final Rate: 0.0004 (near-zero)
  * Suggests a highly stable species

2. Emerging System Characteristics:
- Remarkable homeostatic regulation
- Non-linear, interconnected reaction network
- Rapid initial transients followed by stable equilibrium
- Potential multi-step conversion processes with feedback mechanisms

3. Hypotheses:
- The system likely involves:
  * Cooperative interactions between species
  * Complex regulatory mechanisms
  * Saturation-like behavior
  * Possible enzyme-like conversion processes

4. Key Observations:
- All species converge to near-constant values
- Initial conditions have minimal long-term impact
- Suggests robust, self-regulating biological network

# Iteration 11
## Thoughts
The species correlation matrix reveals profound insights into the system's interactions:

1. Correlation Analysis:
- id_lphe and id_e7i0: Strong Negative Correlation (-0.761)
  * Suggests a direct conversion or competitive relationship
  * As id_lphe increases, id_e7i0 decreases
- id_lphe and id_lrve: Strong Positive Correlation (0.811)
  * Indicates potential co-production or linked metabolic pathway
- id_lphe and id_eqa0: Strong Positive Correlation (0.855)
  * Suggests indirect coupling or shared regulatory mechanism
- id_e7i0 with other species: Negative correlations
  * Implies id_e7i0 is a key regulatory or transitional species

2. Emerging System Characteristics:
- Highly interconnected species
- Complex, non-linear interactions
- Potential multi-step conversion processes
- Robust homeostatic regulation

3. Hypotheses:
- Conversion pathway: id_e7i0 → id_lphe
- Possible parallel production of id_lrve and id_eqa0
- Regulatory mechanisms maintaining species balance
- Potential enzyme-like or catalytic interactions

4. Key Observations:
- Strong correlations suggest intricate metabolic network
- Species concentrations are tightly regulated
- Initial conditions have minimal long-term impact

# Iteration 12
## Thoughts
The latest hypothesis simulation reveals critical discrepancies between our model and experimental observations:

1. Model vs. Experimental Divergence:
- Simulated Final Concentrations:
  * id_lphe: 4.000 (close to experimental ~2.5)
  * id_e7i0: 0.00001 (similar trend)
  * id_lrve: 9.027 (significantly different from experimental ~0.68)
  * id_eqa0: 6.352 (significantly different from experimental ~0.95)

2. Key Observations:
- Conversion mechanism from id_e7i0 to id_lphe appears partially correct
- Cooperative production of id_lrve and id_eqa0 needs refinement
- Current model overestimates production of secondary species
- Suggests more complex regulatory mechanisms are needed

3. Emerging Hypotheses:
- Potential inhibitory mechanisms controlling species production
- Non-linear saturation effects
- Possible feedback loops preventing unlimited growth
- Need for more sophisticated kinetic representations

4. Refinement Strategy:
- Introduce explicit inhibition terms
- Implement more nuanced production constraints
- Consider mass-action and saturation-like kinetics with additional regulatory parameters

# Iteration 13
## Thoughts
The latest simulation reveals continued challenges in precisely modeling the system:

1. Model vs. Experimental Discrepancies:
- Simulated Final Concentrations:
  * id_lphe: 4.000 (vs. experimental ~2.5)
  * id_e7i0: 0.0000003 (similar trend of depletion)
  * id_lrve: 2.730 (vs. experimental ~0.68)
  * id_eqa0: 2.367 (vs. experimental ~0.95)

2. Persistent Challenges:
- Overestimation of secondary species production
- Conversion mechanism shows consistent trend
- Need for more precise regulatory constraints
- Potential missing fundamental interaction mechanisms

3. Emerging Insights:
- System demonstrates remarkable homeostatic properties
- Conversion from id_e7i0 to id_lphe appears fundamental
- Secondary species (id_lrve, id_eqa0) have complex production dynamics
- Likely involves multiple interconnected regulatory processes

4. Refinement Strategy:
- Introduce more sophisticated constraint mechanisms
- Consider explicit rate-limiting steps
- Explore potential hidden intermediate processes
- Implement more nuanced production/consumption balances

# Iteration 14
## Thoughts
The latest simulation provides nuanced insights into the system's behavior:

1. Model vs. Experimental Comparison:
- Simulated Final Concentrations:
  * id_lphe: 2.985 (very close to experimental ~2.5)
  * id_e7i0: 0.00006 (consistent depletion trend)
  * id_lrve: 1.874 (overestimated compared to experimental ~0.68)
  * id_eqa0: 1.935 (overestimated compared to experimental ~0.95)
  * New regulatory_intermediate: 1.015

2. Key Observations:
- Introduction of intermediate species improved lphe concentration accuracy
- Conversion mechanism shows more realistic behavior
- Persistent challenge in precisely modeling secondary species production
- Regulatory intermediate suggests complex multi-step conversion process

3. Emerging Hypotheses:
- Conversion from id_e7i0 involves multiple regulatory steps
- Secondary species (id_lrve, id_eqa0) have complex production mechanisms
- Potential hidden regulatory constraints not yet captured
- System demonstrates robust homeostatic properties

4. Refinement Strategy:
- Focus on precise production/consumption balance
- Explore more sophisticated inhibition and saturation mechanisms
- Consider potential cross-species regulatory interactions
- Implement more nuanced rate-limiting steps

# Iteration 15
## Thoughts
The latest simulation reveals critical insights into the system's complexity:

1. Model vs. Experimental Discrepancies:
- Simulated Final Concentrations:
  * id_lphe: 4.000 (overestimated compared to experimental ~2.5)
  * id_e7i0: 0.000003 (consistent depletion trend)
  * id_lrve: 2.016 (significantly overestimated vs. experimental ~0.68)
  * id_eqa0: 2.089 (significantly overestimated vs. experimental ~0.95)

2. Persistent Modeling Challenges:
- Cross-species regulatory mechanisms did not fully capture system dynamics
- Overproduction of secondary species remains a key issue
- Conversion mechanism shows consistent trend of depletion
- Suggests more fundamental constraints are needed

3. Emerging Hypotheses:
- System likely has:
  * Strong negative feedback mechanisms
  * Rate-limiting steps not yet captured
  * Complex interdependencies between species
  * Potential saturation or inhibition processes

4. Refinement Strategy:
- Implement more sophisticated constraint mechanisms
- Focus on precise balance between production and consumption
- Explore potential hidden regulatory processes
- Consider thermodynamic-like constraints on species interactions

# Iteration 16
## Thoughts
The latest simulation reveals nuanced insights into the system's behavior:

1. Model vs. Experimental Comparison:
- Simulated Final Concentrations:
  * id_lphe: 4.000 (still overestimated vs. experimental ~2.5)
  * id_e7i0: 0.001 (consistent depletion trend)
  * id_lrve: 1.105 (closer to experimental ~0.68, but still overestimated)
  * id_eqa0: 1.139 (closer to experimental ~0.95, but still overestimated)

2. Progress and Persistent Challenges:
- Thermodynamic-like constraints improved model accuracy
- Secondary species production more controlled
- Conversion mechanism remains fundamentally consistent
- Suggests complex, non-linear interactions not fully captured

3. Emerging Hypotheses:
- System likely has:
  * Intricate feedback mechanisms
  * Rate-limiting steps with multiple regulatory points
  * Potential energy-like conservation principles
  * Complex interdependencies between species

4. Key Observations:
- Remarkable consistency in overall system behavior
- Initial conditions have minimal long-term impact
- Strong homeostatic regulation
- Suggests underlying fundamental biological principles

5. Refinement Strategy:
- Focus on precise balance between species
- Explore more sophisticated constraint mechanisms
- Consider potential hidden regulatory processes
- Implement more nuanced production/consumption balances

# Iteration 17
## Thoughts
The simulation encountered a technical error due to unsupported MathML elements, which provides an important insight:

1. Modeling Constraints:
- Current SBML model uses mathematical functions not compatible with Level 2 Version 4
- Need to simplify mathematical expressions
- Suggests we should use more basic mathematical operations

2. Experimental Observations:
- Despite simulation error, experimental data shows consistent patterns:
  * id_lphe: Increases from 1.0 to ~2.48
  * id_e7i0: Decreases from 3.0 to ~0.251
  * id_lrve: Increases from 0.2 to ~0.675
  * id_eqa0: Increases from 0.3 to ~0.95

3. Emerging Insights:
- System demonstrates remarkable homeostatic properties
- Consistent behavior across different initial conditions
- Suggests underlying fundamental regulatory mechanisms
- Conversion and production processes appear highly regulated

4. Refinement Strategy:
- Simplify mathematical expressions
- Use basic algebraic operations
- Implement more straightforward kinetic representations
- Focus on capturing core regulatory principles

# Iteration 18
## Thoughts
The latest simulation reveals continued challenges in precisely modeling the system:

1. Model vs. Experimental Discrepancies:
- Simulated Final Concentrations:
  * id_lphe: 3.987 (overestimated vs. experimental ~2.5)
  * id_e7i0: 0.013 (consistent depletion trend)
  * id_lrve: 2.497 (significantly overestimated vs. experimental ~0.68)
  * id_eqa0: 2.368 (significantly overestimated vs. experimental ~0.95)

2. Persistent Modeling Challenges:
- Simplified model still struggles to capture precise species dynamics
- Overproduction of secondary species remains a key issue
- Conversion mechanism shows consistent trend
- Suggests fundamental constraints are not yet fully understood

3. Key System Characteristics:
- Remarkable homeostatic properties
- Consistent behavior across different initial conditions
- Strong regulatory mechanisms preventing unlimited growth
- Potential hidden feedback loops or rate-limiting steps

4. Emerging Hypotheses:
- System likely has:
  * Complex, non-linear interaction networks
  * Multiple interconnected regulatory mechanisms
  * Potential energy-like conservation principles
  * Sophisticated production/consumption balancing

# Iteration 19
## Thoughts
The system dynamics analysis reveals profound insights into the biological network:

1. Concentration Dynamics:
- id_lphe:
  * Initial mean: 0.647 (high variability)
  * Final mean: 2.478 (extremely consistent)
  * Rate of Change: +1.830 (significant increase)
- id_e7i0:
  * Initial mean: 3.368 (high variability)
  * Final mean: 0.251 (extremely consistent)
  * Rate of Change: -3.117 (significant decrease)
- id_lrve:
  * Initial mean: 0.653 (moderate variability)
  * Final mean: 0.672 (minimal change)
  * Rate of Change: +0.020 (near-zero)
- id_eqa0:
  * Initial mean: 0.747 (moderate variability)
  * Final mean: 0.949 (minimal change)
  * Rate of Change: +0.202 (slight increase)

2. Key System Characteristics:
- Remarkable homeostatic regulation
- Consistent final states despite varied initial conditions
- Strong conversion mechanism from id_e7i0 to id_lphe
- Subtle, controlled production of secondary species

3. Emerging Hypotheses:
- Complex, multi-step conversion processes
- Intricate feedback and regulatory mechanisms
- Potential energy-like conservation principles
- Non-linear interactions with precise balancing

4. Refinement Strategy:
- Focus on capturing the core conversion mechanism
- Implement precise regulatory constraints
- Explore minimal model representation
- Emphasize system's inherent stability

# Iteration 20
## Thoughts
The simulation encountered a technical error, but the experimental data provides crucial insights:

1. Consistent System Dynamics:
- Remarkable stability across all experiments
- Species converge to nearly identical final states:
  * id_lphe: Increases from 0.1 to ~2.48
  * id_e7i0: Decreases from 4.0 to ~0.251
  * id_lrve: Increases from 1.0 to ~0.673
  * id_eqa0: Decreases from 1.0 to ~0.949

2. Key System Characteristics:
- Strong homeostatic regulation
- Conversion mechanism from id_e7i0 to id_lphe
- Controlled production of secondary species
- Minimal dependence on initial conditions

3. Final Modeling Insights:
- System demonstrates complex, interconnected dynamics
- Likely involves multiple regulatory mechanisms
- Conversion process appears fundamental
- Secondary species show subtle, controlled changes

4. Proposed Biological Interpretation:
- id_e7i0 serves as a primary substrate
- id_lphe acts as a key regulatory product
- id_lrve and id_eqa0 represent downstream regulated species
- Potential metabolic or signaling network
