Alias: L- α- Aminoisovaleric acid
Molecular formula: C5H11NO2
Molecular weight: 117.15
Properties: white monoclinic crystal or crystalline powder, and those recrystallized with ethanol water solution are colorless plate like or phosphorus flake like crystals. Odorless, with special bitter taste. The melting point is about 315 degrees. The pH value of 5% aqueous solution is 5.5-7.0. It is stable to heat, light and air. It is easily soluble in water (8.85g/100ml, 25 ° C) and almost insoluble in ethanol and ether. It is difficult to separate leucine from leucine.
Use: L-valine is an essential amino acid for human body and one of the three branched chain amino acids. Because of its special structure and function, L-valine plays a particularly important role in human life metabolism. It is also used to strengthen food.
