Task: Please create a text description for a molecule based on its representation.
SMILES: CC[C@](O)(C(C)=O)C(=O)O
Constraint: Answer the question with complete sentences.
Result: The molecule is a 3-oxo monocarboxylic acid that is butanoic acid in which the hydrogens at position 2 are replaced by an acetyl and a hydroxy group (the S enantiomer). It is a 3-oxo monocarboxylic acid, a hydroxy monocarboxylic acid and a tertiary alpha-hydroxy ketone. It derives from a butyric acid. It is a conjugate acid of a (S)-2-acetyl-2-hydroxybutanoate.
