[Ontogenic characteristics of changes in fatty acid composition of the liver lipids as a main substrate for peroxidation in geese].
Dynamics of fatty acid composition of geese liver lipids in embryogenesis and early postnatal period has been investigated. High nonsaturation of these tissues lipids is shown during all the period of researches. It is established, that in the second half of embryogenesis and in the beginning of postnatal period (first two weeks) the increase of oleic acid contents is observed with simultaneous decrease of the contents of the polynonsaturated fatty acids (PUFA) showing properties of endogenous bioregulators (arachidonic acid (AA), docosahexaenoic acid [figure: see text] (DHA). From the two-weeks age of gosling the contents of the mentioned acids changes in the opposite direction. The coordination of dynamics of TBA-active products with nonsaturation of fatty acids (FA) expressed in mEqu/g concerning double bonds, and also with respect to AA/DHA has been revealed.
