Product description:
L-Tert-Leucine is one of the eight essential amino acids of the human body. It belongs to the fatty group of amino acids in 20 protein amino acids. It is called three branched amino acids together with l-isoleucine and l-valine. It is enantiomeric with d-leucine, and it is white glossy hexahedral crystal or white crystalline powder at room temperature. It is odorless, slightly bitter. In the presence of hydrocarbons, it is stable in aqueous solution of inorganic acids. It is soluble in 40ml water and about 100ml acetic acid per gram. Very slightly dissolved in ethanol or ethyl ether, soluble in formic acid, dilute hydrochloric acid, basic hydroxide and carbonate solutions.
