Task: Please create a text description for a molecule.
SMILES: CCCCCCCC/C=C\CCCCCCCCCCCC(=O)O[C@H](COC(=O)CCCCCCCCCCCCCCCCCCC)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 eicosanoyl and (13Z)-docosenoyl respectively. It derives from an icosanoic acid and an erucic acid.
