L-Lysine Use and Manufacturing

Methods of Manufacturing

1. L-lysine is generally supplied in the market with L-lysine hydrochloride [657-27-2]. The free L-lysine is highly susceptible to deliquescence and is susceptible to deterioration due to the presence of free amino groups. To stimulate the smell, difficult to long-term preservation. L-lysine hydrochloride is relatively stable, easy to deliquescence, easy to save. However, the demand for L-lysine in some applications is also increasing, such as peptide synthesis chemistry, biochemical research, lysine derivative preparation and the like. The free L-lysine can be prepared from L-lysine hydrochloride.
2. Tobacco: BU, 22; FC, 21; can be derived from animal protein hydrolysis. Also can be synthesized from benzophenopiperidine.

Uses

A moderate serotonin antagonist and essential amino acid.

Material

Calcium hydroxide

Sodium hydroxide

Urea

Activated charcoal

Hydrochloric acid

Ammonia

Sulfuric acid

Starch
