What is L-Cystine?

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

L-Cystine Benefits:

L-cysteine may help prevent the exercise-related production of free radicals, which are shown to contribute to oxidative stress and damage cells. The amino acid acts as an antioxidant. A form of cysteine called L-cysteine may help treat arthritis and hardening of the arteries. It may help treat certain lung diseases. These include bronchitis, emphysema, and tuberculosis. Cysteine may play a role in the normal growth rate of hair. However, most of the clinical trials used to test L-cysteine have focused on the effects of a related compound called N-acetyl-l-cysteine.

  • Amino Acid
  • Hair, Skin & Nails
