It is supposed that at stages of phylogenesis seven biological functions was developed: 1) biological function of trophology; 2) homeostasis; 3) endoecology; 4) adaptation; 5) continuation of species; 6) locomotion; 7) cognitive function, including intellect. The function of trophology (feeding) is implemented by two biological reactions: exophilia - external feeding and endophilia - internal feeding. The function of endoecology prevents exceeding of upper limit of physiological interval by no substrate, catabolites and endogenous phlogogens. It is implemented by two biological functions: excretion and inflammation. The etiological factors of atherosclerosis are the following ones. The oleic mono-saturated fatty acid in chemical reactions is by far more active than palmitic fatty acid. In the ocean, all animals were carnivorous (piscivorous); species Homo Sapiens, in millions of years of life on dry land, forcedly became a herbivorousone. The main role in development of herbivorous animals belongs to insulin; the hormone regulating in the first-place metabolism of fatty acids, expresses transmutation of all endogenously synthesized from glucose palmitic saturated fatty acid in oleic monosaturated fatty acid. The late in phylogenesis insulin can't initiate transmutation of exogenous palmitic saturated fatty acid of food into oleic mono-saturated fatty acid. Under effect of insulin in vivo an active oleic type of metabolism of fatty acids is developed; and outside if effect of insulin palmitic type of metabolism of fatty acids is developed. In the ocean, synthesis of active eicosanoids occurs from ῳ-3 polyene fatty acids; there is no such fatty acids in dry land. The basis of pathogenesis of atherosclerosis is feeding of large amount of carnivorous (meat) food by phylogenetically herbivorous Homo Sapiens. This way a deficiency of palmitic saturated fatty acids in cells if developed blocking their bio-accessibility. The lipoproteins of low density are not developed in the initiated by insulin transfer of oleic triglycerides to cells in oleic apoE/B-100 lipoproteins of very low density and their absorption by cells. The transfer of triglycerides into lipoproteins of very low density is blocked under slow processes of transmutation of palmitic lipoproteins of very low density into lipoproteins of low density, retention cumulation of lipoproteins of low density in blood. Only because of partial utilization by monocytes of non-ligand palmitic lipoproteins of very low density →lipoproteins of low density that occurs in the intima of arteries of elastic type, atheromotosis is developed. The atheromotosis masses of intima are first of all interim catabolites of polyene fatty acids; the cells could not to absorb them by apoB-100-endocytosis in the content of lipoproteins of low density. The atherosclerosis, hyperlipoproteinemia, high content of lipoproteins of low density in blood and deficiency of polyene fatty acids in cells are a result of disorder of trophology function; the atheromotosis of arteries is only partial implementation of endoecology function.
据推测,在系统发育阶段发展出了七种生物学功能:1)营养生物学功能;2)稳态;3)内生态学;4)适应;5)物种延续;6)运动;7)认知功能,包括智力。营养生物学功能(进食)通过两种生物学反应实现:外食癖——外部进食和内食癖——内部进食。内生态学功能可防止无底物、分解代谢产物和内源性致炎物质使生理区间上限超标。它由两种生物学功能实现:排泄和炎症。动脉粥样硬化的病因如下。化学反应中的油酸单不饱和脂肪酸远比棕榈酸活跃。在海洋中,所有动物都是肉食性的(食鱼性的);智人在陆地上生活的数百万年里,被迫变成了草食性动物。草食性动物发育中的主要作用属于胰岛素;这种激素首先调节脂肪酸代谢,表现为所有由葡萄糖内源性合成的棕榈酸饱和脂肪酸转化为油酸单不饱和脂肪酸。在系统发育后期,胰岛素无法启动食物中外源棕榈酸饱和脂肪酸向油酸单不饱和脂肪酸的转化。在体内胰岛素的作用下,会形成活跃的油酸型脂肪酸代谢;而在体外,没有胰岛素作用时则会形成棕榈酸型脂肪酸代谢。在海洋中,活性类二十碳烷酸由ω-3多烯脂肪酸合成;陆地上没有这种脂肪酸。动脉粥样硬化发病机制的基础是系统发育上的草食性智人大量食用肉食。这样就会导致细胞内棕榈酸饱和脂肪酸缺乏,阻碍其生物可及性。低密度脂蛋白不会在胰岛素启动的油酸甘油三酯向极低密度的油酸载脂蛋白E/B-100脂蛋白转移并被细胞吸收的过程中形成。在极低密度的棕榈酸脂蛋白缓慢转化为低密度脂蛋白的过程中,甘油三酯向极低密度脂蛋白的转移受阻,低密度脂蛋白在血液中滞留积聚。仅因为弹性型动脉内膜中单核细胞对极低密度的非配体棕榈酸脂蛋白→低密度脂蛋白的部分利用,才会发生动脉粥样化。内膜的动脉粥样化团块首先是多烯脂肪酸的中间分解代谢产物;细胞无法通过低密度脂蛋白中的载脂蛋白B-100内吞作用吸收它们。动脉粥样硬化、高脂蛋白血症、血液中低密度脂蛋白含量高以及细胞内多烯脂肪酸缺乏是营养生物学功能紊乱的结果;动脉粥样化只是内生态学功能的部分体现。
