L-Cysteine monohydrochloride Usage And Synthesis
Chemical Propertiessolid
UsesAs dough conditioner.
UsesL-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.
DefinitionChEBI: A hydrochloride obtained by combining L-cysteine with one molar equivalent of hydrogen chloride.
General DescriptionL-cysteine is a sulfur-containing amino acid.
Biochem/physiol ActionsNMDA 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 MethodsLikely 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.]
