Task: Please create a text description for a molecule based on its representation.
Molecule SMILES: CCCCCCCCCCCCC/C=C/[C@@H](O)[C@H](COC(=O)CCCCCCCCCCCCCCCCC)NC(C)=O
Constraint: Answer the question with full sentences.
Result: The molecule is a 1-O-acyl-N-acylsphingosine in which the N- and O-acyl groups are specified as acetyl and stearoyl (octadecanoyl) respectively. It derives from a N-acetylsphingosine and an octadecanoic acid.
