Usage
|
L-valine is an essential amino acid for the human body. It is used in biochemical research, the preparation of tissue culture media, and as an amino acid medication. As a nutritional supplement, it can serve as a main component of amino acid infusions and comprehensive amino acid preparations. Being one of the three branched-chain amino acids (BCAAs) and an essential amino acid, L-valine can be used to treat liver failure and central nervous system dysfunction.
