[Age-related reference values for serum triacylglycerol subfractions]

In connection with the increased importance of serum triacylglycerols (TAG) in atherogenesis and with a view to their eventual changes wth age, their subfractions were studied in practically healthy subjects via thin-layer chromatography. Comparative assessments for "norm" of TAG-subfractions are elaborated according to saturation rate, depending on age, and sex. No regular sex differences were established in the rest age groups. With age advancing reduction of S3 was established for both sexes, of MD2--for females and M3--for males and increase of M2 in females and D2 in males. In quantitative respect, for both sexes, most frequent are MD and M2, followed by S2M and SD2. The saturated fatty acids predominate at 1 and 3 positions of TAG in practically healthy subjects and at 2 position--unsaturated fatty acids.
