Task: Please create a description for a molecule.
Molecule SMILES: CCCCCCCCCCCCCCCCCC(=O)OC[C@@H](O)COP(=O)([O-])OC[C@H](NC(=O)CCCCCCCCCCCCCCC)C(=O)[O-]
Constraint: Answer the question with full sentences.
Result: The molecule is an anionic phospholipid obtained by deprotonation of the carboxy and phosphate groups of N-hexadecanoyl-O-(1-octadecanoyl-sn-glycero-3-phospho)-L-serine; major species at pH 7.3. It is a conjugate base of a N-hexadecanoyl-O-(1-octadecanoyl-sn-glycero-3-phospho)-L-serine.
