L-Valine
Description
Essential branched-chain amino acid that inhibits lipid peroxidation and enhances the accessibility of fat-soluble reactive oxygen species (ROS) for scavenging. The hydrophobic branched-chain side chain of valine partitions into lipid-rich environments (sebum, membrane bilayers), enabling antioxidant protection in the lipid phase of the skin. Component of the free amino acid antioxidant pool.
Function
