title: Estimation of N-amino-N,N-dimethylaminoethanol, choline and their acetate esters by gas chromatography mass spectrometry.
abstract: A method is described for measurement of choline, N-aminodeanol, and their acetyl esters by gas chromatography mass spectrometry. The preparation of N-aminodeanol and its isotopic variants is also described. This method allows a thorough quantitative analysis of the replacement of true with false neurotransmitter in biological preparations.
