Notes:
Methane chemical ionization (CI) gas chromatography mass spectrometry (GCMS) has been used to study choline chloride esters of 16C, 17C and 18C fatty acids and the β-acetoxy derivative of palmitylcholine chloride (Pahutoxin). All choline esters recorded [M—CH3CI]+ as their highest mass ion and m/z 72 [CH2—CH2—N+(CH3)2] as the base peak. Transmethyiation generated the methyl esters of the 16C-18C fatty acids and in the case of the β-acetoxy derivative of the 16C choline ester chloride the α:β -unsaturated 16C methyl ester was the major product. Mild hydrolysis of β-acetoxypalmitylcholine chloride yielded β-acetoxypalmitic acid.
