L-Lysine Chemical Properties,Uses,Production

Description

See ι-LYSINE MONOCHLORIDE.

Chemical Properties

L-Lysine is an essential amino acid (a protein building block) that cannot be produced by the body from other nutri ents. It helps ensure adequate absorption of calcium and the formation of collagen for bone, cartilage and connective tissue. This compound is odorless.

Occurrence

Some natural food sources for l-lysine include lima beans, kidney beans, potatoes, corn, red meat, fish and milk.

Uses

L-Lysine is an essential amino acid used in human nutrition. It plays a vital role in calcium absorption, building muscle protein and recovering from surgery or sports injuries. It is used for the treatment of herpes infections and cold sores. Its derivatives lysine acetylsalicylate is utilized to treat pain as well as to detoxify the body after heroin use. It is an important additive to animal feed. Further, it is used in many foods, especially red meats, fish and dairy products.

Preparation

Produced by fermentation. Also produced by use of continuous ion exchange technology.

Definition

ChEBI: An L-alpha-amino acid; the L-isomer of lysine.

General Description

L-Lysine is a basic amino acid.

Safety Profile

An experimental teratogen. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of NOx.

Purification Methods

Crystallise L-lysine from aqueous EtOH. [Greenstein & Winitz The Chemistry of the Amino Acids J. Wiley, Vol 3 pp 2097-2122 1961, Kearley & Ingersoll J Am Chem Soc 73 5783 1951, Beilstein 4 IV 2717.]
