Chemical Information

Name

L-Lysine

Description

Dietary supplement, nutrient. Found widely in protein hydrolysates, e.g. casein, egg albumen, fibrin, gelatin, beet molasses. Flavouring agent for a variety of foods Lysine (abbreviated as Lys or K) is an alpha-amino acid with the chemical formula HO2CCH(NH2)(CH2)4NH2. It is an essential amino acid, which means that the human body cannot synthesize it. Its codons are AAA and AAG. L-Lysine is found in many foods, some of which are rocket salad (sspecies), lingonberry, japanese persimmon, and welsh onion.
