User: I want to create a molecule SMILES.
Assistant: This sounds very interesting. Should I consider any constraints for the creation?
User: Yes, please. The molecule can be described as:
The molecule is a sulfonium betaine obtained by deprotonation of the carboxy groups and protonation of the amino group of S-adenosyl-S-carboxymethyl-L-homocysteine. Major microspecies at pH 7.3 It is a L-alpha-amino acid zwitterion and a sulfonium betaine. It is a conjugate base of a S-adenosyl-S-carboxymethyl-L-homocysteine.
Assistant: Ok, here you go, this SMILES fits this description: Nc1ncnc2c1ncn2[C@@H]1O[C@H](C[S+](CC[C@H]([NH3+])C(=O)[O-])CC(=O)[O-])[C@@H](O)[C@H]1O
