English name: L-Leucine
Molecular formula: C6H13NO2
Molecular weight: 131.17
Introduction: L-leucine, also known as leucine, chemically called a monoamino-isocaproic acid, was first isolated by Proust in 1819 from cheese, and later Braconnot crystallized from acid hydrolysates of muscle and wool, and named leucine. L-leucine is one of the 18 common amino acids, and is called Branched chain amina acids (BCAA) because the molecular structure of L-leucine, L-isoleucine, and L-oxine contains a methyl side chain.
