Task: Please generate a SMILES based on the text description.
Description: The molecule is a tripeptide zwitterion resulting from the transfer of a proton from the carboxy group to the amino group of Gly-Gly-Ile. Major microspecies at pH 7.3. It is a tautomer of a Gly-Gly-Ile.
Result: CC[C@H](C)[C@H](NC(=O)CNC(=O)C[NH3+])C(=O)[O-]
