Abstract

Somatic cells at the early stages of phylogenesis realized the metabolism of long-chain fatty acids (FA), primarily palmitic saturated FA. It dominated the construction of a bilayer cell membrane and as a substrate for oxidation in mitochondria during energy production. Later, polyene FAs became involved in the construction of the cell membrane, the membranes of intracellular organelles, and became the substrate for the synthesis of biologically active eicosanoids. At later stages of phylogenesis, the metabolism of medium-chain FAs is activated and the formation of ketone bodies as a substrate, which is available for oxidation by the mitochondria of the formed cells of the nervous tissue in the absence of first substrate glucose. In the later stages of phylogenesis, insulin initiated: a) the transformation of carnivorous ancestors of the species Homo sapiens in the ocean into a herbivorous species while living on land; b) the formation of the new biological function of locomotion and c) the dominance of the oleic variant of the metabolism of long-chain fatty acids with higher kinetic parameters of mitochondria oxidation. Metabolites of medium chain FA have become humoral mediators of metabolism and the formation of feedback mec...Continue Reading
