Task: Please create a description for a molecule based on its representation.
SMILES: CCC(=O)N[C@@H](CCSC)C(=O)[O-]
Constraint: Answer the question with complete sentences.
Result: The molecule is an N-(fatty acyl)-L-alpha-amino acid anion that is the conjugate base of N-propanoyl-L-methionine, obtained by deprotonation of the carboxy group; major species at pH 7.3. It is a N-(fatty acyl)-L-alpha-amino acid anion and a N-(fatty acyl)-L-methionine(1-). It is a conjugate base of a N-propanoyl-L-methionine.
