cysteine
Disulfide bond former
Cysteine is an amino acid found in most proteins, notable for its sulfur-containing side chain.
The sulfur allows cysteine molecules to form disulfide bonds with each other, creating cross-links that stabilize protein structures—crucial for keratin in hair and nails.
Cysteine appears in supplements and is used industrially as a dough conditioner in baking.
