Mw of cysteine
Cysteine is a semiessential proteinogenic amino acid with the formula HOOC−CH(−NH2)−CH2−SH. The thiol side chain in cysteine often participates in enzymatic reactions as a nucleophile. Cysteine is chiral. Only L-cysteine is found in nature. The thiol is susceptible to oxidation to give the disulfide derivative cystine, whic… WebCarboxamidomethyl (on Cysteine and other residues) 58: Carboxymethyl (on Cysteine and other residues) 60: sodium + potassium: 64: Selenocysteine (from Serine) 67: Asp transamidation with piperidine: 68: 3,5-Dichlorination (of Tyrosine with 35Cl) 69: Dehydroalanine (Dha) 70:
