    Glossary Cystine

    amino acid formed by linking two cysteine molecules

    Cystine is an amino acid that forms when two cysteine molecules are linked by a disulfide bond. It is important for the structural stability of proteins, particularly in keratin, which is a key component of hair, skin, and nails. This bond helps maintain the strength and rigidity of these proteins, contributing to the overall health and resilience of hair and other tissues.
