L-leucine, also known as leucine, is α-amino-γ-methylvaleric acid, α-aminoisocaproic acid, and its molecular formula is C6H13O2N.

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.
