Task: Please give me a SMILES based on the description below.
Description: The molecule is dizwitterionic form of homocystine arising from transfer of two protons from the carboxy to the amino groups; major species at pH 7.3. It has a role as a human metabolite. It is a tautomer of a homocystine.
Result: [NH3+]C(CCSSCCC([NH3+])C(=O)[O-])C(=O)[O-]
