Task: Please create a text description for a molecule.
Molecule SMILES: CCCCCCCCCCCCCCCC/C=C\CC/C=C\CCCC(=O)O[C@H](COC(=O)CCCCCCCCCCCCCCC)COP(=O)([O-])OCC[N+](C)(C)C
Constraint: Answer the question with full sentences.
Result: The molecule is a phosphatidylcholine 42:2 in which the acyl groups specified at positions 1 and 2 are hexadecanoyl and (5Z,9Z)-hexacosadienoyl respectively. It derives from a hexadecanoic acid and a (5Z,9Z)-5,9-hexacosadienoic acid.
