General description

Pyridoxal-phosphate (PLP, pyridoxal-5′-phosphate, P5P) is a prosthetic group of some enzymes. It is the active form of vitamin B6, which comprises three natural organic compounds, pyridoxal, pyridoxamine and pyridoxine. PLP acts as a coenzyme in all transamination reactions, and in some decarboxylation and deamination reactions of amino acids.

Vitamin B6, Pyridoxal and Pyridoxine in Cell Culture

This page segues to comprehensive insights on how Vitamin B6, Pyridoxal and Pyridoxine affect the performance of serum-free, protein-free cell culture systems used for biomanufacturing heterologous proteins including monoclonal antibodies. The page introduces the in vitro chemistry and biochemistry of pyridoxal, pyridoxine.

Insulin Signaling and Energy Homeostasis

Glucose metabolism is regulated by the opposing actions of insulin and glucagon. Insulin is released from pancreatic ß cells in response to high blood glucose levels and regulates glucose metabolism through its actions on muscle, liver, and adipose tissue.
