Summary
Metabolic physiologists use stable isotopes to trace biosynthesis. This study demonstrates Monte Carlo spreadsheet analysis for modeling complex multi-species isotope enrichment during synthesis.
Area of Science:
- Biochemistry
- Metabolic Physiology
- Computational Biology
Background:
- Stable isotopes are crucial tools for metabolic physiologists to track biosynthesis.
- Labeling molecules with stable isotopes alters their mass, enabling tracking of newly synthesized material.
Purpose of the Study:
- To implement and analyze stable isotope tracing in biosynthesis using Monte Carlo simulation on spreadsheets.
- To model the complex process of multi-species isotope enrichment during biosynthesis.
Main Methods:
- Utilized Monte Carlo analysis on a spreadsheet for modeling isotope biosynthesis.
- Simulated the condensation of two acetate moieties to synthesize acetoacetate using natural and 13C enriched acetate.
- Employed repetitive, simultaneous Boolean calculations to capture multi-species isotope dynamics.
Main Results:
- Monte Carlo spreadsheet modeling effectively captures the complexity of multi-species isotope biosynthesis.
- Demonstrated the impact of increasing synthesized molecule count on the model's goodness of fit compared to analytical solutions.
Conclusions:
- Spreadsheet-based Monte Carlo analysis provides a viable method for studying complex isotope biosynthesis.
- The model's accuracy improves with a larger number of synthesized molecules, validating the approach.
