User: I'm looking for the SMILES of a molecule that can be described as:
The molecule is a cationic sphingoid that is the conjugate acid of 4-hydroxy-15-methylhexadecasphinganine, obtained by protonation of the amino group; major species at pH 7.3. It is a conjugate acid of a 15-methylhexadecaphytosphingosine.
Assistant: This is a molecule that fits your description: CC(C)CCCCCCCCCC[C@@H](O)[C@@H](O)[C@@H]([NH3+])CO
