From food intake triglyceride, called exogenous fatty. Endogenous means fat from the body sugars, such as free fatty acids come into the fatty material.
         The liver is the organ of human metabolism, in the three substances that carbohydrate, lipid and protein metabolism. Liver mainly involved in the synthesis of endogenous fat and transshipment. Liver cells in the blood from the main uptake of free fatty acids, glucose metabolism in the uptake of blood to the conversion of free fatty acids, another synthetic triglyceride, and cholesterol ester, phospholipids. Fatty liver can not be stored, so its synthetic fat and timely manner and a very low density lipoprotein in the blood to the transit. Peripheral organizations fat intake, storage and mobilization in the postprandial mainly from the digestion and absorption of exogenous fatty, from hunger, the number of endogenous synthesis of liver fat. Visibility of lipid metabolism in the liver plays an important role in dynamic equilibrium.
