L-Cystine belongs to the amino acid group and is found to be optically active due the presence of chiral centers and a wide range of hydrogen bonding network, which tends to enhance its optical properties. It can serve as an important source of L-cysteine and other sulfur containing amino acids, thus acting like a substitute for L-methionine.
