Product Detail

Product description:L-leucine (L-leucine) is also known as leucine, namely α-amino-γ-methylvaleric acid, α-aminoisocaproic acid, and its molecular formula is C6H13O2N. In 1Chemicalbook 819, Proust was first isolated from cheese. Later, Braconnot crystallized from the acid hydrolysate of muscle and wool and named it leucine.

ECHEMI Editorial Reference

L-Leucine is an essential branched-chain amino acid (BCAA), which activates the mTOR signaling pathway[1].
Solid|Small white lustrous plates or crystalline powder; odourless
L-leucine is the L-enantiomer of leucine. It has a role as a plant metabolite, an Escherichia coli metabolite, a Saccharomyces cerevisiae metabolite, a human metabolite, an algal metabolite and a mouse metabolite. It is a pyruvate family amino acid, a proteinogenic amino acid, a leucine and a L-alpha-amino acid. It is a conjugate base of a L-leucinium. It is a conjugate acid of a L-leucinate. It is an enantiomer of a D-leucine. It is a tautomer of a L-leucine zwitterion.|An essential branched-chain amino acid important for hemoglobin formation.|Leucine is one of nine essential amino acids in humans (provided by food), Leucine is important for protein synthesis and many metabolic functions. Leucine contributes to regulation of blood-sugar levels; growth and repair of muscle and bone tissue; growth hormone production; and wound healing. Leucine also prevents breakdown of muscle proteins after trauma or severe stress and may be beneficial for individuals with phenylketonuria. Leucine is available in many foods and deficiency is rare.
