Glucose
General infotmation:
Glucose is the main source of energy for tissues in the body and the most common indicator of the state of carbohydrate metabolism. Maintaining blood sugar levels within certain limits is very important for the proper functioning of all organs and tissues in the human body. While some of these - fat, liver, muscle cells can use as a source of energy other than glucose and other substrates (eg fatty acids), others for red blood cells, central nervous system, etc. glucose is the only source of energy. The brain cells can not synthesize glucose or store it as a backup form, which is why it needs to be continuously delivered with blood. This requires a constant level of blood sugar, which should not be lowered with increased expenditure, or increased with increased carbohydrate delivery. This maintenance of the blood sugar level within certain limits is accomplished by the central nervous system and especially its higher departments in the cerebral cortex, by a number of hormones, among which the main place is the insulin secreted by the pancreas and other factors. In healthy subjects, fasting blood glucose levels are for venous blood from 3.8 to 6.1 mmol / l and for capillaries from 3.5 to 5.5 mmol / l. Blood glucose levels rise 1-2 hours after eating. Numerous diseases are those in which blood sugar can be pathologically elevated or decreased. The greatest incidence and significance among these diseases is diabetes mellitus, in which there is a sustained increase of glucose above the established normal values.
