詳細

詳細

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.

This certified reference material (CRM) is produced and certified in accordance with ISO/IEC 17025 and ISO 17034. This CRM is traceable to primary material from an NMI, e.g. NIST or NMIJ.
