Task: Please create a description for a molecule based on its representation.
SMILES: CCCCCCCC/C=C\CCCCCCCC(=O)OC[C@H](COP(=O)([O-])OCC[N+](C)(C)C)OC(=O)CCCCCCCCCCCCCCCCCCC
Constraint: Answer the question with complete sentences.
Result: The molecule is a phosphatidylcholine 38:1 in which the acyl groups at positions 1 and 2 are specified as (9Z)-octadecenoyl and eicosanoyl respectively. It derives from an icosanoic acid and an oleic acid.
