Studies in chemical ionization mass spectrometry: V—localization of homoconjugated triene and tetraene units in aliphatic compounds

Abstract

Abstract The homoconjugated triene (‘linolenic acid unsaturation’) and tetraene (‘arachidonic acid unsaturation’) pattern can be readily recognized and localized in aliphatic compounds by chemical ionization (NO) mass spectrometry. This method may be used for the screening of biological material, especially in food analysis.
