What is L-Cystine?
L-Cystine, also known as cystine, is an oxidized union of two molecules of simpler forms. The cysteine amino acid links two cysteine residues with a bond that pertains to amino acids.Cysteine and cystine are very similar. One can turn one into the other and vice versa. Cystine acts as an antioxidant and prevents radiation in skeletal tissues and skin.
