User: I'm looking for the SMILES of a molecule that can be described by:
The molecule is the cationic sphingoid resulting from the protonation of the amino group of sphingosine. It has a role as a human metabolite. It is a conjugate acid of a sphingosine. It is an enantiomer of a L-erythro-sphingosine(1+).
Assistant: This is a molecule that fits this description: CCCCCCCCCCCCC/C=C/[C@@H](O)[C@@H]([NH3+])CO
