Task: Please create a description for a molecule based on its representation.
Molecule SMILES: CCCCCCCC/C=C\CCCCCCCC(=O)O[C@H](COC(=O)CCCCCCCCCCCCCCCCCCCCCCC)COP(=O)([O-])OCC[N+](C)(C)C
Constraint: Answer the question with complete sentences.
Result: The molecule is a phosphatidylcholine 42:1 in which the acyl groups specified at positions 1 and 2 are tetracosanoyl and (9Z)-octadecenoyl respectively. It derives from an oleic acid and a tetracosanoic acid.
