Etymology

Cys is the short form of cysteine, and that name comes from the Greek kystis meaning 'bladder', because chemists first found it in bladder stones. So today Cys is the usual abbreviation for that amino acid in proteins, the one that can join with another Cys to make a strong 'disulfide' link.
