✦ Synopsis

Oils 46, 49, and 56 are rather old samples of marine oils with high levels of poly-unsaturated component fatty acids, which may be partially conjugated and/or autoxidized. The anomalous behaviour of rice oil (oil 48) is attributed to the high percentage of free fatty acids present.

be very good.

In the other oils, however, where we may expect the composition to be closer to a mixture of triglycerides with non-conjugated, non-polymerized, straight-chain component fatty acids, the concurrence between observed and computed sound velocities may be considered to

Studies on the Fatty Acids in the Feather Waxes of some Water-Birds

By Dr. G . O d l t a m

Inslitute of Medical Biodientistry.

In a systematic study on the free flowing exudate of the preen gland in living water-birds, the secretion of domestic goose, Peiping duck (Anas platyrhynchos L.) and mute swan (Cygnus olor) have been investigated. The structure and composition of the branched chain acids present, as determined by mass spectrometry and gas chromatography, are reported.

The purpose of this work was to study the effect of a culinary process, deep-fat frying, on fatty acids profiles of different meat dishes. Content in fatty acids in three meat dishes (chicken breast, pork steak, and pork loin), before and after deep-fat frying, was analyzed. Results showed an increa

The first question that must be answered before the determination of the structure of nucleic acids can be carried out in earnest is: how much of what do they contain? It seemed to us that procedures suitable for this purpose had been lacking in the past and that no real progress was possible, unles
