Appearance
: Cysteine is white crystal or crystalline powder, soluble in water, slightly smelly, and insoluble in ethanol, insoluble in ether and other organic solvents. Melting point 240 ¡É, the monoclinic system. As one of the sulfur amino acid cysteine, is a non-essential amino acids in vivo by the sulfur atom of the methionine and serine hydroxyl oxygen atom relative to replacement through cystathionine synthesis, starting from the cysteine to generate glutathione glycylglycine. Cysteine acid is stable in neutral and alkaline solution, easily oxidized to cystine.
Use
: 1. Cosmetics: for the production of the perm refined, sunscreen, perfume, hair raising fine, this cysteine replaced by a sulfur-based acid perm fine, perm lotion, with easy to perm, hair is easy to maintain, flexible without disorder and other advantages, can also be formulated sunscreen and germinal perfume
Two. In medicine: cysteine for liver medicine, antidote, expectorant drugs and other pharmaceuticals. Cysteine and its derivatives can be used for the detoxification of the liver poisoning, antipyretic and analgesic, ulcer treatment, recovery from fatigue, infusion and comprehensive amino acid preparations, especially for the expectorant
the treatment of bronchitis and phlegm.
3. In the food: bread fermentation enhancers, preservatives. Cysteine as fermentation additives, milk and juice with antioxidants and stabilizers, as well as the pet animal matter nutritional additives
