L-Cystine 是一种从半胱氨酸氨基酸硫醇侧链氧化获得的含硫衍生物。它起到抗氧化剂的作用，保护组织免受辐射和污染，减缓衰老过程。它还有助于蛋白质合成。

Not considered one of the 20 amino acids, Cystine is a sulfur-containing derivative obtained from oxidation of cysteine amino acid thiol side chains. It functions as an antioxidant and protects tissues against radiation and pollution, slowing the aging process. It also aids protein synthesis. Cystine is abundant in many proteins of skeletal tissues and skin, and found in insulin and digestive enzymes chromotrypsinogen A, papain, and trypsinogen.
