L-Leucine with CAS No:61-90-5 is an impurity standard of Leucine. Leucine is an essential branched-chain amino acid with a chemical structure classified as an aliphatic, alpha-amino acid. It is one of the nine essential amino acids that the human body cannot synthesize independently and must be obtained through the diet. Leucine plays a crucial role in protein synthesis, serving as a building block for the formation of proteins in cells. As a branched-chain amino acid (BCAA), leucine is particularly important in supporting muscle protein synthesis and aiding in the maintenance and repair of muscle tissues. Additionally, leucine is involved in energy metabolism and has been studied for its potential role in various physiological processes, including insulin signaling and regulation of blood sugar levels. Dietary sources rich in leucine include meat, dairy products, soybeans, and certain nuts and seeds. Buy high quality L-Leucine from from Molsyns Research.
