hemical Properties:White crystalling powder or white crystals.Odorless,slightly bitter taste.Freely soluble in formic acid,sparingly soluble in water,very slightly soluble in ethanol or in ether, dissoves in dilute hydrochloric acid.
Usage:L-leucine is not synthesized in animals, hence it must be ingested, usually as a component of proteins. It is synthesized in plants and microorganisms via several steps starting from.
As a dietary supplement, leucine has been found to slow the degradation of muscle tissue by increasing the synthesis of muscle proteins. Leucine is utilized in the liver, adipose tissue, and muscle tissue. In adipose and muscle tissue, leucine is used in the formation of, and the combined usage of leucine in these two tissues is seven times greater than its use in the liver.
