User: Can you create the SMILES of a molecule based in this description:
The molecule is a ketoaldonic acid that is butyric acid carrying an oxo substituent at position 2 as well as two hydroxy substituents at positions 3 and 4 (the S-enantiomer). It is a dihydroxy monocarboxylic acid, a 2-oxo monocarboxylic acid, a ketoaldonic acid and a secondary alpha-hydroxy ketone. It derives from a butyric acid. It is a conjugate acid of a (S)-3,4-dihydroxy-2-oxobutanoate. It is an enantiomer of a (R)-3,4-dihydroxy-2-oxobutanoic acid.
Assistant: Of course, here you go: O=C(O)C(=O)[C@@H](O)CO
User: Can you {#give me|create|generate!} the {SMILES__description} of a molecule based in this description:

Assistant: {#Yes|Of course|Sure|Yes, I'm happy to help!}, here you go: {SMILES#}
O=C(O)C(=O)[C@@H](O)CO
