Description
L-Cystine is a sulfur-containing amino acid dimer formed by the oxidation of cysteine. It serves as an antioxidant and is a key structural component in many proteins, including those in skin, skeletal tissues, and digestive enzymes. Research applications include studies of oxidative stress, protein synthesis, and cellular protection mechanisms in both in vitro and in vivo models.

Chemical Information

(-)-Cystine

L-cystine is the L-enantiomer of the sulfur-containing amino acid cystine. It has a role as an EC 1.2.1.11 (aspartate-semialdehyde dehydrogenase) inhibitor, a flour treatment agent, a mouse metabolite, a Saccharomyces cerevisiae metabolite and a human metabolite. It is a cystine, a non-proteinogenic L-alpha-amino acid and a L-cysteine derivative. It is a conjugate acid of a L-cystine anion. It is an enantiomer of a D-cystine. It is a tautomer of a L-cystine zwitterion.
