Abstract
The article presents the results of laboratory studies of the fatty acid composition of the subcutaneous fat of ringed seal (Phoca hispida), harvested in the Arctic regions of Yakutia. Identification and determination of the concentration of fatty acids in the samples was carried out using the method of gas-liquid chromatography with a mass spectrometric detector, methyl esters of fatty acids were obtained by acid hydrolysis with sulfuric acid in methanol. A comparison of the subcutaneous fat of two types of seals (Phoca (PUSA) Sibirica Gmel and Phoca hispida) and fish oil, as sources of omega-3 polyunsaturated fatty acids. The adipose tissue of the ringed ringed seal (Phoca Hispida) contains up to 40 % of the polyunsaturated fatty acids of the total number of fatty acids in the fatty tissue, which is 25 % more than that of the Baikal seal (Phoca (PUSA) Sibirica Gmel), and 56 % more than in fish oil. The data obtained in this work indicate the uniqueness of the fat of the ringed seal as a raw material for the creation of drugs aimed at the treatment and prevention of diseases of the cardiovascular system.
