L-Cysteine monohydrochloride Chemical Properties,Uses,Production
Chemical Properties
solid
Uses
As dough conditioner.
Uses
L-Cysteine hydrochloride, anhydrous is widely used as additive in food production. It is used as an antioxidant to promote fermentation and keep the flavor. It is also used in cosmetics and animal feed.
Definition
ChEBI: A hydrochloride obtained by combining L-cysteine with one molar equivalent of hydrogen chloride.
General Description
L-cysteine is a sulfur-containing amino acid.
Biochem/physiol Actions
NMDA glutamatergic receptor agonist that is also an agonist at AMPA glutamatergic receptors at high concentrations.
Safety Profile
: Moderately toxic by intraperitoneal, intravenous, and possibly other routes. Mutation data reported. When heated to decomposition it emits very toxic fumes of NOx, SOx, and Cl-.
Purification Methods
Likely impurities are cystine and tyrosine. Crystallise the salt from MeOH by adding diethyl ether, or from hot 20% HCl. Dry it under vacuum over P2O5. Hygroscopic. [Beilstein 4 III 1580, 1600.]
