Transamination

Hypoxic tissues are various tissues and organs that are deficient in oxygen. A typical example is brain tissue. Normally, the blood delivers 20% of oxygen to the brain, from which up to 50-60% of exhaled air enters as reduced hemoglobin, the rest as nitrate ion. This is a direct relationship. The inverse relationship is due to the fact that the body has two systems that contribute to the respiratory or oxidative pathway when it is necessary to use oxygen or oxygen plus fuel: the Krebs cycle and carbohydrate glycolysis. By reducing the excess supply of oxygen to the tissues, hypoxia does not occur. And with a lack of oxygen, tissue hypoxia develops, the so-called hypoxic/oxidative form of general cell damage.
