Disease Roles
Cystine Overview
Cystine is a naturally occurring, non-essential amino acid formed by the oxidation of two cysteine molecules, joined by a disulfide bond. It plays important structural and functional roles, including stabilizing protein structures through disulfide bridges and acting as a component of connective tissues. Excessive urinary excretion can lead to the formation of cystine stones, a rare type of kidney stone associated with cystinuria.

Safety Considerations
- Excessive urinary excretion leading to cystine stones
- No specific conditions increase dietary need if adequate protein intake is maintained.
