Studies on Fatty Acid Composition of Siberian Marmot (Marmota Sibirica Radde, 1862) Fat

Fatty acid composition of Siberian marmot fat (Marmota Sibirica, tarbagan) has been studied; the basic physicochemical parameters have been determined. 36 fatty acids have been identified, about 90 % among those being represented by palmitic, oleic, linoleic and linolenic acids. A comparative analysis of the composition of tarbagan’s hypodermic, abdominal and brown fat was carried out. It has been established that for the kinds of fat under investigation the composition of acids is variable, and the greatest differences in the concentration of saturated acids are inherent in brown fat. An unusually high fat unsaturation level for land species of animals observed for a Siberian marmot might cause the fat biological activity.
