What is l leucine ?
l leucine, also known as leucine, is chemically called α-aminoisohexanoic acid, which was first isolated from cheese in 1819. Later, Braconnot got its crystal from the acid hydrolysate of muscle and wool, and named it l leucine. It is one of the eighteen common amino acids and one of the eight essential amino acids for human body. It belongs to the aliphatic amino acids in 20 kinds of protein amino acids, and it is called three branched-chain amino acids together with L- isoleucine and L- valine. l leucine powder is an enantiomer with D- leucine, and it is white shiny hexahedron crystal or white crystalline powder at room temperature. Odorless, slightly bitter. In the presence of hydrocarbons, it is stable in inorganic acid aqueous solution.

It can promote the secretion of growth hormone, can be used to promote the secretion of sex hormones, and can also be used to enhance the metabolism of alcohol, which belongs to a health care product. It is an amino acid needed by human body, which cannot be synthesized and needs to be ingested from food. If it is insufficient in the past, l leucine powderwill easily affect growth hormone, and even promote the secretion of acetaldehyde dehydrogenase and alcohol dehydrogenase, which can reduce the stimulation of alcohol on the liver. It can be extracted from seafood such as crabs, oysters, shrimps, etc., so as to increase the amount of amino acids in the body, which is beneficial to physical fitness.
