Question:

The amino acid cysteine has the structure shown:
The amino acid cysteine has the structure shown:
(a) A second

(a) A second sulfur-containing amino acid called cystine (C6H12N2O4S2) is formed when cysteine undergoes biological oxidation. Suggest a reasonable structure for cystine.
(b) Another metabolic pathway converts cysteine to cysteine sulfinic acid (C3H7NO4S), then to cysteic acid (C3H7NO5S). What are the structures of these two compounds?
