1. Cysteine

   Cysteine (symbol Cys or C; ) 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. When present as a deprotonated catalytic residue, sometimes the symbol Cyz is used. The deprotonated form can generally be described by the symbol Cym as well. The thiol is susceptible to oxidation to give the disulfide derivative cystine, which serves an important structural role in many proteins. In this case, the symbol Cyx is sometimes used. When used as a food additive, it has the E number E920. Cysteine is encoded by the codons UGU and UGC. The sulfur-containing amino acids cysteine and methionine are more easily oxidized than the other amino acids.

1. cysteine

   Cysteine is a semi-essential sulfur-containing amino acid derived from protein digestion, including dairy products, meat, grains, and legumes. It plays crucial roles in protein structure, detoxification, and diverse metabolic pathways. It is unique among amino acids in that it contains a sulfur atom, which allows it to form disulfide bonds that help maintain the structure and stability of proteins. Cysteine is also an essential component of the antioxidant glutathione and may have a role in the prevention of chronic diseases. It may be taken as a dietary supplement for its potential health benefits.

1. Cysteine

   Cysteine is an α-amino acid with the chemical formula HO2CCHCH2SH. It is a semi-essential amino acid, which means that it can be biosynthesized in humans. The thiol side chain in cysteine often participates in enzymatic reactions, serving as a nucleophile. The thiol is susceptible to oxidization to give the disulfide derivative cystine, which serves an important structural role in many proteins. When used as a food additive, it has the E number E920.
