        L-Cysteine hydrochloride monohydrate Chemical Properties,Uses,Production

        Chemical Properties

        white crystalline powder

        Uses

        L-Cysteine is a non-essential amino acid that can be synthesized by the human body under normal physiological conditions if a sufficient quantity of methionine is available. L-Cysteine is commonly use d as a precursor in the food and pharmaceutical industries. L-Cysteine is used as a processing aid for baking, as an additive in cigarettes, as well as in the preparation of meat flavours.

        Definition

        ChEBI: A hydrate that is the monohydrate form of L-cysteine hydrochloride.

        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.]
