Stability of unsaturated methyl esters of fatty acids on surfaces.
The stability of unsaturated methyl esters is greater when they are adsorbed on silica gel than when a glass surface is used. Storage of small samples adsorbed on silica gel may be a convenient addition to conventional methods of protecting labile fats against autoxidation.
متن کاملFatty acids in bovine milk fat
Milk fat contains approximately 400 different fatty acid, which make it the most complex of all natural fats. The milk fatty acids are derived almost equally from two sources, the feed and the microbial activity in the rumen of the cow and the lipids in bovine milk are mainly present in globules as an oil-in-water emulsion. Almost 70% of the fat in Swedish milk is saturated of which around 11% ...
متن کاملIsolation and determination methods for brain cerebrosides, hydroxy fatty acids, and unsaturated and saturated fatty acids *
A new method is described for the isolation of nearly pure total cerebrosides from fresh brain. Florisil columns are used to separate the cerebroside hydroxy and normal acids, in the form of their esters, and to separate the saturated and unsaturated esters of each group. The esters within each class are determined by gas chromatography, the hydroxy esters being run as the methyl ethers. Yields...
متن کاملThe Component Fatty Acids of Goat Milk Fat
Milk fats from different species of mammals are known to vary considerably in chemical composition. In early work, the butter fat constants were largely used to indicate the differences in composition. More recently, emphasis has been placed on comparisons of the component fatty acids of the various types of butter fats. The methods available for separation of the acids are not conducive to hig...
