Biochemical Pathways & Stoichiometric Modeling — Hands-on

Learn how to convert biochemical pathway diagrams into mathematically consistent models using stoichiometric representations. You will construct reaction networks, build stoichiometric matrices, apply mass balance constraints, and prepare models in standard formats suitable for downstream flux balance and systems biology simulations.
