- Аннотация: It is rational, according to biology laws and purposes for which cells use fatty acids, to distinguish between saturated (without double bonds in chain), monoene (with one bond), unsaturated (with 2 and 3 double bonds) and polyene (with 4, 5 and 6 double bonds) acids. The saturated and monoene fatty acids are mainly the substratum for oxygenation and working out of energy by cells. The unsaturated fatty acids are the substratum for formation of membranes. The polyene fatty acids are the predecessors of synthesis of eicosanoids and aminophosphotides. With subject to characteristics of metabolism and transfer in vivo, the fatty acids are subdivided into short chain C4 - C8 and medium chain C-10 - C-14 fatty acids. The etherification occurs with glycerin into "short" triglycerides which are not bounded with apoproteins. The long chain fatty acids form "long" triglycerides which in enterocytes are structured by apoprotein B-48 into composition of chylomicrons. It is possible to validly consider that difference in outflow from enterocytes to veins of portal system (which includes veins of omentum) of medium chain fatty acids in the form of short triglycerides can directly input into pathogenesis of syndrome of isolated omental obesity and metabolic syndrome. The another input into the mentioned conditions is the secretion through ductus thoracicus into large veins of greater systemic circulation of long chain fatty acids in the form of triglycerides in the content of chylomicrons. The omental obesity is the only specific symptom of metabolic syndrome.
