Determination of isotopic purity and position in deuterated methyl behenate

In the course of preparing peanut oil type triglycerides for metabolism studies, methyl esters of deuterated behenic acid, a saturated 22-carbon fatty acid, with zero, two, and six deuterium atoms were synthesized. The specific positions of deuterium atoms and the completion of deuteration in the products were characterized by gas chromatography/mass spectrometry methods. (author)
