Task: Please create a text description for a molecule.
SMILES: CCCCC/C=C\C/C=C\C/C=C\CCCCC(=O)OC[C@H](COP(=O)([O-])OCC[N+](C)(C)C)OC(=O)CCCCCCCCCCCCC/C=C\CCCCCCCC
Constraint: Answer the question with complete sentences.
Result: The molecule is a phosphatidylcholine 42:4 in which the acyl groups specified at positions 1 and 2 are (6Z,9Z,12Z)-octadecatrienoyl and (15Z)-tetracosenoyl respectively. It derives from a gamma-linolenic acid and a (15Z)-tetracosenoic acid.
