✦ Synopsis

Abstract

The following samples of biological origin were submitted to transesterification by means of methanolic hydrogen chloride, generated from methanol and acetyl chloride: triglycerides from black currant oil, butter, pig lard tissue, fat tissue of inner part of goose, lyophilized human blood plasma, larvae of fleshfly of the genus Sarcophaga, lipid A from Shigella dysenteriae, esters from beeswax and esters from the cuticular lipids of pea aphid Acyrthosiphon pisum. Attention was also paid to sterol esters and to free fatty acids. Conditions of transesterifications are discussed, as well as the conditions of gas chromatographic analysis of components after transesterification.

A system was designed for chemiluminescent measurement of lipid hydroperoxides by their site-specific reaction in sodium dodecylsulfate micelles. Ferrous ion-induced decomposition of lipid hydroperoxides in the sodium dodecylsulfate micelles resulted in strong chemiluminescence of the Cypridina luci
