It's a test that measures the amount of lactic acid (also called "lactate") in your blood. This acid is made in muscle cells and red blood cells. It forms when your body turns food into Lactate is the end product of anaerobic metabolism. Lactate is generated mainly in skeletal muscle, brain, erythrocytes, the skin and the gut and is disposed of by gluconeogenesis in the liver and by complete oxidation. Lactic acidosis can be due to excessive lactate formation or decreased removal. Lactic acid is mainly produced in muscle cells and red blood cells. It forms when the body breaks down carbohydrates to use for energy when oxygen levels are low. Times when your body's oxygen level might drop include: A test can be done to measure the amount of lactic acid in the blood. Lactate is a key energy substrate in skeletal muscle fibers, providing us with sufficient energy during exercise. Lactate increases the number of mitochondria (the energy powerhouses of cells) in muscle cells. Lactate plays a key role in supplying energy for cognitive functioning during exercise. Lactic acid is a chemical your body produces when your cells break down carbohydrates for energy. You might see it referred to as lactate. Muscle cells and red blood cells make the most lactic acid, but it can come from any tissue in your body. Most people think of lactic acid in their muscles during a tough workout. Cite Share Subject Physiology - Other Issue Section: Articles Key points Blood lactate concentrations reflect the balance between lactate production and clearance. Glycolysis, gluconeogenesis and pyruvate conversion to and from lactate are linked with NAD + and NADH. pGvHh.
