Cysteine from WACKER - Wacker Chemie AG

L-Cysteine

L-Cysteine is one of the 20 natural amino acids and is the only one that contains a sulfhydryl group (– SH) in the side chain . This is highly chemically reactive and forms disulfide bridges which lend proteins much of their stability and are responsible, for example, for the strong fiber strands of hair, wool, feathers, nails, hooves and horn. A large proportion of the keratins, i.e. the protein, in these materials consists of cysteine.
