Etymology

Cystine comes from the Greek root kystis meaning 'bladder' or 'sac', because it was first found in bladder stones, and the chemical ending -ine marks it as a kind of molecule. So the name helps you remember that cystine is an amino acid that contains sulfur and appears in proteins like hair and nails.
