L-Valine is a naturally occurring, essential branched-chain amino acid (C5H11NO2, CAS 72-18-4) the human body cannot synthesize. Its branched isopropyl side chain gives it a hydrophobic character and groups it with leucine and isoleucine as the three BCAAs; it is purely glucogenic in metabolism.
L-Valine is a standard component of BCAA and general amino acid dietary supplements, sports nutrition, and total parenteral nutrition formulations. In animal nutrition it’s a recognized limiting amino acid added to livestock and pet-food premixes. It’s also a routine cell-culture media additive and pharmaceutical synthesis raw material.
