    Abstract:
    The blood composition of non-etherized fatty acids (NEFA) was studied in 22 patients with metabolic syndrome (MS) and 11 healthy individuals. The qualitative NEFA composition presented by 31 components of individual fatty acids was analyzed, by taking into account of glucose-insulin homeostatic changes in MS patients: those without insulin resistance (IR) (Group 1) and those with diagnosed IR (Group 2). MS patients with normal insulinemia were ascertained to have lower levels of lauric, myristic, palmitic, C24:0, C16:0i acids. With a decrease in the relative quantity of saturated NEFA, the levels of polyunsaturated fatty acids (FA) increased. The proportions of linoleic (C18:2 omega 6) and linolenic (C18:3 omega 3) acids doubled (p < 0.01), arachidonic acid (C20:4 omega 6) was observed to tend to rise. The cumulative FA index sigma omega 6 increased twofold. In Group 1, the integrated index of changes in the FA series (unsaturation index) was 41% higher than that in the control group (p < 0.05). In Group 2, the vector of changes in the relative quantity of NEFA was similar, but impairments were less marked than that in Group 1. The findings suggest that the development of insulin resistance is preceded by impaired blood cell transfer and absorption of NEFA.
