Audited Supplier [Product name]: L-Leucine feed grade
[Chemical[ formula]: C6H13NO2
[CAS]: 61-90-5
[Product performance]:
L-leucine is not synthesized in animals, hence it must be ingested, usually as a component of proteins. It is synthesized in plants and microorganisms via several steps starting from.
As a dietary supplement, leucine has been found to slow the degradation of muscle tissue by increasing the synthesis of muscle proteins. Leucine is utilized in the liver, adipose tissue, and muscle tissue. In adipose and muscle tissue, leucine is used in the formation of, and the combined usage of leucine in these two tissues is seven times greater than its use in the liver.

L-Isoleucine added to feed as a nutritional supplement can promote poultry growth. In the 20 common amino acids that form the basic building blocks of proteins, leucine (Leu), isoleucine (Ile) and valine (Val) three kinds of amino acids on the structure has the same branch side chain, is called branched chain amino acids (branched - chain amino acid, BCAA), on which the carbon chain is a set with the structure of the branched chain aliphatic neutral amino acids.BCAA is aquatic animal body can't synthesis and must gain amino acids from foods, namely the essential amino acids, BCAA is a special kind of amino acid, it is the only major in extrahepatic tissue oxidation of essential amino acids, mainly oxidation parts in muscles, their catabolism mainly in skeletal muscle.
