Task: Please create a description for a molecule.
Molecule SMILES: CCCCCCCCCCC/C=C/[C@@H](O)[C@H](CO[C@@H]1O[C@H](CO)[C@H](O)[C@H](O)[C@H]1O)NC(=O)CCCCCCCCCCCCCCCCCCCCC
Constraint: Answer the question with full sentences.
Result: The molecule is a galactosylceramide obtained by formal condensation of the carboxy group of docosanoic acid with the amino group of beta-D-galactosyl-(1<->1')-hexadecasphingosine. It has a role as a marine metabolite. It derives from a hexadecasphing-4-enine and a docosanoic acid.
