Task: Please create a text description for a molecule.
SMILES: CCCCCCCCCCCCC/C=C/[C@@H](O)[C@H](COP(=O)([O-])OCC[N+](C)(C)C)NC(=O)CCCCCCCCCCCCCC
Constraint: Answer the question with complete sentences.
Result: The molecule is a sphingomyelin d18:1 in which the amino group of sphingosine is substituted by a pentadecanoyl group. It has a role as a mouse metabolite. It is a sphingomyelin d18:1 and a sphingomyelin 33:1. It derives from a pentadecanoic acid.
