L-Lysine
Properties : colorless crystalline needle. Melting point: 224-225 ° C , easily soluble in water and very soluble in alcohol-not soluble in ether.
Production Methods : L-lysine generally L-lysine hydrochloride [657-27-2] supply market, free L-lysine vulnerable deliquescence, with their free amino easily degenerate Wong, and stimulating flavor and are difficult to keep for long. L-lysine hydrochloride is relatively stable, and not deliquescence facilitate preservation. But L-lysine in some uses are also increasing the demand, such as peptide synthesis of chemical and biochemical research, preparation of derivatives such as lysine. Free L-lysine can be L-lysine hydrochloride preparation.
Application : Lysine is a human and animal growth must be one of the amino acids in a transfusion, nutritional medicine, food and feed additives have an important purpose
Packing: 25KG/Drum, 25MT/1*20'FCL
