Coenzyme A sodium salt hydrate is widely used in biochemical research and enzymatic studies due to its role as a cofactor in acyl transfer reactions. It plays a critical part in metabolic pathways, including the citric acid cycle, fatty acid synthesis, and oxidation. In laboratory settings, it is employed to study enzyme kinetics and mechanisms, particularly those involving acetyl-CoA and other acyl-CoA derivatives. It is also utilized in the production of pharmaceuticals and bioactive compounds where acyl group transfer is essential. Additionally, it finds application in diagnostic assays to measure enzyme activity and metabolic function in clinical and research contexts.
