What is L-Leucine?

L-leucine is an essential amino acid with the molecular formula $C_6H_{13}NO_2$, and it is classified as one of the branched-chain amino acids (BCAAs). At room temperature, it appears as white crystals or powder with a slightly bitter taste. Melting point is 293–295°C, slightly soluble in ethanol, and is insoluble in ether. In living organisms, it is synthesized under the catalysis of acetohydroxyacid synthase (AHAS). Leucine also acts as a signaling molecule, participating in the regulation of various physiological activities.
