User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a cationic sphingoid obtained by the protonation of the amino group of 14-methylhexadecasphingosine; major species at pH 7.3. It is a conjugate acid of a 14-methylhexadecasphingosine.
Assistant: This is a molecule that fits your description: CCC(C)CCCCCCCC/C=C/[C@@H](O)[C@@H]([NH3+])CO
