User: I want to create a SMILES.
Assistant: This sounds very exciting. Should it be a special one?
User: Yes, the molecule can be described as:
The molecule is a sphing-4-enine in which the double bond is trans. It has a role as a human metabolite and a mouse metabolite. It is a conjugate base of a sphingosine(1+). It is an enantiomer of a L-erythro-sphingosine.
Assistant: Ok, here you go, this SMILES fits your description: CCCCCCCCCCCCC/C=C/[C@@H](O)[C@@H](N)CO
