Abstract. The liver is the main organ in the cells of which biochemical transformations of the products of the digestive hydrolysis of carbohydrates occur and their conversion into glucose — a form available to the cells of the body. The liver is a depot of carbohydrates, since part of the glucose is stored here in the form of glycogen. The liver maintains blood glucose at a constant level — this is the glucostatic function of the liver. With an excess of glucose in the liver, glycogen synthesis from glucose occurs — glycogenesis. After eating a carbohydrate-rich meal, the glycogen content can be up to 8% of the liver weight.
