In tests conducted on rats the process of eliminating the endogenous formed lipids with bile was studied and the discovered changes were contrasted against the lipids metabolism disorders in the liver and blood of the animals receiving rations with differing quantitative and qualitative content of carbohydrates. A balanced ration with saccharose led to a higher quantity and radioactivity of the total lipids and triglycerides in the liver and blood. In the bile a fall in the level of the cholic acid, cholesterol and the lipid complex and an increased radioactivity in the composition of the lipids complex, cholesterol and phospholipids were observed. A ration with an elevated level of starch did not upset the lipids metabolism in the liver and blood. In the bile the lipids complex decreased, the quantity of cholic acid increased, while the radioactivity in the lipids complex and phospholipids was rising. A carbohydrate-rich ration with saccharose raised the content of total lipids, triglycerides and of the ether-bound blood cholesterol and their radioactivity. The described diet resulted in an increased amount of the bile and in a drop therein of the level of the lipids complex, cholesterol and phospholipids and in an accrued radioactivity in them.
