Metabolite Identification
Common NamePalmitoylcholine
DescriptionPalmitoylcholine, also known as choline palmitate or hexadecanoylcholine, belongs to the class of organic compounds known as acyl cholines. These are acylated derivatives of choline. Choline or 2-hydroxy-N,N,N-trimethylethanaminium is a quaternary ammonium salt with the chemical formula (CH3)3N+(CH2)2OH. Palmitoylcholine has been identified in blood and the human placenta (PMID: 31396400 , 32033212 ).
