S-Alkyl substituted cysteines and their sulphoxides (I) Structure These compounds comprise a large number of cysteine derivatives in which the thiol hydrogen is replaced by various aliphatic residues. The basic structure is R - S - CH2-CH.(NH2).COOH where R represents the aliphatic residue, which may range in size from methyl to 2-carboxy-1,1-dimethylethyl. The corresponding sulphoxides of the structurally simpler compound are also known to occur naturally, an example of these being S-methyl-L-cysteine.pdfen-NZhttps://www.wgtn.ac.nz/library/about-us/policies-and-strategies/copyright-for-the-researcharchiveBiochemistryTextAll rights, except those explicitly waived, are held by the Author
