Abstract

Balanced diet during 60-day hypokinesia leads to inhibition of lipoprotein lypase (LPLA) and liver triglyceride lypase (L-TGLA) activity of the rat blood serum. The level of very low density lipoproteins (VLDLP) grows, and suppression of lecithin-cholesteryl-acyltransferase (LCAT) activity is accompanied by reduction of the share of cholesterol derivatives with polyunsaturated fatty acids. Combined effects of protein-vitamin insufficiency and hypokinesia result in parversion of the lipolysis processes, that manifests in prevalence of L-TGLA over LPLA. The levels of VLDLP increase, and growth of LCAT activity is acompanied by the growth of cholesteryl linoleate share and level. Hypokinesia combined with the studied experimental diets was found to lead to increase of the free fatty acid level and to decrease of the blood serum levels of phospholipids and triglycerides.
