Glycine, serine and threonine metabolism

Glycine, serine and threonine metabolism (CAS No.: 600-18-0) is a short-chain keto acid derivative commonly identified as 2-oxobutanoic acid, an endogenous intermediate generated during the enzymatic cleavage of cystathionine within amino acid metabolic networks. As a member of the glycine, serine, and threonine metabolic pathway, this compound plays a critical role in linking sulfur amino acid metabolism with central carbon metabolism, contributing to downstream processes such as energy production and biosynthetic flux. It is frequently utilized in biochemical and metabolomic studies to investigate transamination reactions, mitochondrial function, and metabolic pathway regulation, particularly in systems examining amino acid catabolism and redox balance. Although direct molecular targets are not typically defined, its role as a substrate or intermediate implicates interactions with aminotransferases and dehydrogenases that govern metabolic flux. In vitro studies generally employ this compound in concentration ranges spanning low micromolar to millimolar levels depending on the experimental system, enabling its use in enzyme kinetics, pathway reconstitution assays, and cellular metabolic profiling. In research settings, it is applied in cell-based and in vivo models to probe alterations in amino acid metabolism under physiological and stress-related conditions, with dosing parameters adjusted according to specific experimental objectives and model requirements.
