Abstract

AbstractThe 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.
