User: I'm looking for the SMILES of a molecule that can be described as:
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.
Assistant: This is a molecule that fits this description: CCCCCCCCCCCCC/C=C/[C@@H](O)[C@H](COC(=O)CCCCCCCCCCCCCCCCC)NC(C)=O
