Task: Please create a text description for a molecule based on its representation.
SMILES: CCCCC/C=C\C/C=C\C/C=C\C/C=C\CCCC(=O)O[C@H](COC(=O)CCCCCCCCCCCCCCCC)COP(=O)([O-])OCC[N+](C)(C)C
Constraint: Answer the question with complete sentences.
Result: The molecule is a phosphatidylcholine 37:4 in which the acyl substituents at positions 1 and 2 are specified as heptadecanoyl and arachidonoyl respectively. It derives from an arachidonic acid and a heptadecanoic acid.
