Background:

  • Metabolic system regulation by external effectors (inhibitors, hormones) is crucial.
  • Qualitative elasticity analysis and quantitative regulation analysis are existing methods.
  • Quantitative regulation analysis is complex and has limited practical application.

Purpose of the Study:

  • To develop mathematical relationships for quantifying effector impacts on metabolic systems.
  • To simplify the practical application of regulation analysis.
  • To link finite changes in system variables to effector-induced changes in metabolic process activity.

Main Methods:

  • Derivation of mathematical relationships between system variables and process activity.
