The composition of fatty acids of human adipose tissue reflects the composition of fatty acids in diet [5, 7, 8 Lack of data concerning the composition of fatty acids in adipose tissue of Poles made us undertake such studies. As there are no literature data available on triglyceride composition of human adipose! tissue we decided to include this subject in our investigations.
Material and methodsSamples of perirenal adipose tissue were collected during anatomopathological examination at Medical Academy in Bialystok (North-East Poland). There were analysed 32 samples -18 from men, 14 from women; 10 from people aged between 41-60,22 from people aged between 61-91.Fat was extracted from tissue according to Folch et al. [9]. Fatty acid composition after methylation according to Peisker [I61 was determined with GLC in a gas chromatograph Pye Unicam 104 with FID joined with a recorder (Philips) and integrator Pye Unicam DP-88. To identify fatty acids and triglycerides standards from Applied Sci. Lab. were applied. Mean values in groups determined by sex and age were compared with t-Student test [6].
ResultsAnalysed fat was clearly dominated by oleic and palmitic acids. For the whole population their values were 52.9 and 21.9 % respectively ( Table 1). Two age groups did not differ in fatty acid compsition, but differences were observed between sexes. Fat from male adipose tissue had a lower content of oleic acid and higher of myristic one than that from female adipose tissue.Triglycerides were dominated by compounds with 52, 54 and 50 carbon atoms. For the whole population their mean values were 39.7, 24.6 and 21.8 46 respectively (Table 2). Again, age did not affect the triglyccride composition of adipose tissue and differences were observed between sexes. For male group the share of triglycerides CM and c50 was higher, that of triglyceride CM -lower.
