Biochemistry.
- : a crystalline amino acid, C6H12O4N2S2, occurring in most proteins, especially the keratins in hair, wool, and horn, and yielding cysteine on reduction.

This action is due chiefly to its progressive formation of calcium sulphydrate from the cystine group of the softer keratins.
Ammonia, therefore, dissolves the cystine without entering into chemical union with it.
Potash also readily dissolves cystine, as do also oxalic acid and the strong mineral acids.
