Task: Please create a description for a molecule based on its representation.
SMILES: CCCCC/C=C\C/C=C\CCCCCCCC(=O)OCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC(=O)N[C@@H](CO)[C@H](O)/C=C/CCCCCCCCCCCCC
Constraint: Answer the question with full sentences.
Result: The molecule is an N-acylsphingosine in which the ceramide N-acyl group is specified as 30-[(9Z,12Z)-octadeca-9,12-dienoyloxy]triacontanoyl. It is a N-acylsphingosine and an omega-linoleoyloxy-O-ultra-long chain acylceramide.
