SIMPLE QUANTITATIVE TRANSESTERIFICATION OF LIPIDS .2. APPLICATIONS

The following samples of biological origin were submitted to transeste rification by means of methanolic hydrogen chloride, generated from me thanol and acetyl chloride:triglycerides from black currant oil, butte r, pig lard tissue, fat tissue of inner part of goose, lyophilized hum an blood plasma, larvae of fleshfly of the genus Sarcophaga, lipid A f rom Shigella dysenteriae, esters from beeswax and esters from the cuti cular lipids of pea aphid Acyrthosiphon pisum. Attention was also paid to sterol esters and to free fatty acids. Conditions of transesterifi cations are discussed, as well as the conditions of gas chromatographi c analysis of components after transesterification.
