CAS No.: 61-90-5
Molecular Formula: C6H13NO2 Molecular Weight: 131.17
Molecular Structure:
Property:
The melting point of Leucine is 286-288 ºC and the sublimation is 145-148 ºC. The alpha of
Leucine is 15.4 º (c=4, 6N HCl) and the water solubility is 22.4g/l (20 ).
Leucine is a branched-chain amino acid (BCAA) since
Leucine possesses an aliphatic side-chain that is non-linear. Racemic
Leucine had been subjected to circularly polarized synchrotron radiation in order to better understand the origin of biomolecular asymmetry. An enantiomeric enhancement of 2.6 % had been induced, indicating a photochemical origin of homochirality of biomolecules.

Usage:
As a dietary supplement, Leucine has been found to slow the degradation of muscle tissue by increasing the synthesis of muscle proteins in aged rats.
Leucine is utilized in the liver, adipose tissue, and muscle tissue. In adipose and muscle tissue,
Leucine is used in the formation of sterols, and the combined usage of
Leucine in these two tissues is seven times greater than its use in the liver.
In yeast genetics, mutants with a defective gene for
Leucine synthesis (leu2) are transformed with a plasmid that contains a working
Leucine synthesis gene (LEU2) and grown on minimal media.
Leucine synthesis then becomes a useful selectable marker.
Package and Storage:
Leucine is packed 25kg fiber drum and stored in cool and air place.
