Task: Please create a description for a molecule.
Molecule SMILES: CCCCCCCC/C=C\CCCCCCCC(=O)OC[C@H](COP(=O)([O-])OCC[N+](C)(C)C)OC(=O)CCCCCCCCCCCCCCCCCCCCCCC
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 (9Z)-octadecenoyl and tetracosanoyl respectively. It derives from a tetracosanoic acid and an oleic acid.
