Task: Please create a text description for a molecule based on its representation.
SMILES: [NH3+]C(CCS)C(=O)[O-]
Constraint: Answer the question with complete sentences.
Result: The molecule is an amino acid zwitterion of homocysteine arising from transfer of a proton from the carboxy to the amino group; major species at pH 7.3. It has a role as a human metabolite, an Escherichia coli metabolite and a Saccharomyces cerevisiae metabolite. It is a tautomer of a homocysteine.
