[{"from": "human", "value": "Use the given information to create a molecule that fulfills the desired purpose. The molecule is the L-enantiomer of the sulfur-containing amino acid cystine. It has a role as a flour treatment agent, a human metabolite, a Saccharomyces cerevisiae metabolite, a mouse metabolite and an EC 1.2.1.11 (aspartate-semialdehyde dehydrogenase) inhibitor. It is a cystine, a L-cysteine derivative and a non-proteinogenic L-alpha-amino acid. It is a conjugate acid of a L-cystine anion. It is an enantiomer of a D-cystine. It is a tautomer of a L-cystine zwitterion."}, {"from": "gpt", "value": "[C][Branch1][#Branch2][C@@H1][Branch1][=Branch1][C][=Branch1][C][=O][O][N][S][S][C][C@@H1][Branch1][=Branch1][C][=Branch1][C][=O][O][N]"}]
