Task: Please create a text description for a molecule based on its representation.
Molecule SMILES: CC(=O)N[C@@H](CSC(=O)[C@]1([C@@H](O)C(C)C)NC(=O)[C@H](C)[C@@H]1O)C(=O)O
Constraint: Answer the question with complete sentences.
Result: The molecule is l-Cysteine substituted at nitrogen by an acetyl group and at sulfur by a substituted-lactam carbonyl group. It is a lactam and a S-substituted L-cysteine.
