L-leucine, also known as leucine, is α-amino-γ-methylvaleric acid, α-aminoisocaproic acid, and its molecular formula is C6H13O2N. L-leucine is one of the eight essential amino acids for the human body. It belongs to the aliphatic amino acids in the twenty protein amino acids. Together with L-isoleucine and L-valine, it is called the three major branched chain amino acids. It is an enantiomer with D-leucine, and it is a white glossy hexahedral crystal or a white crystalline powder at room temperature. Odorless, slightly bitter. In the presence of hydrocarbons, it is stable in aqueous mineral acid. Dissolve each gram in 40ml of water and about 100ml of acetic acid. Very slightly soluble in ethanol or ether, soluble in formic acid, dilute hydrochloric acid, alkaline hydroxide and carbonate solutions.

L-hydroxyproline is a non essential amino acid, which means that it is made of other amino acids in the liver; It does not have to be obtained directly through diet. L-hydroxyproline is necessary for the construction of collagen, the main structural protein of human body.
