Task: Please create a description for a molecule.
Molecule SMILES: CCCCCCCCCCCC/C=C/[C@@H](O)[C@H](CO)NC(=O)CCCCCCCCCCCCCCCCCCCCCCC
Constraint: Answer the question with full sentences.
Result: The molecule is a ceramide that is the N-tetracosanoyl derivative of C17-sphingosine. It is a N-acylheptadecasphingosine, a Cer(d41:1) and a N-(very-long-chain fatty acyl)-sphingoid base. It derives from a C17 sphingosine(1+) and a tetracosanoic acid.
