  • Essay / ketone body - 1508

    IntroductionEnergy production is an essential live performance. Ketone synthesis provides a vital approach to survival and prolonging human life when the body is isolated from regular energy supplements or normal energy metabolism pathways are disrupted, for example, prolonged starvation, uncontrolled diabetes, and extreme diet. fatty and inadequate in carbohydrates. admission. The liver mainly takes responsibility for the production of ketone bodies called ketogenesis from fatty acids in cases of low glucose levels. The ketone bodies produced are acetone, acetoacetic acid and β-hydroxybutyric acid, the two water-soluble components of which are transmitted to organs such as the brain, skeletal muscles, myocardium and kidneys through the blood circulation to be used as energy sources. Although ketogenesis is vital for the brain because the brain can only use glucose or ketone bodies as energy sources in an emergency, an excessively high level of ketone bodies in the blood can cause acidosis which can cause serious conditions in patients, such as coma. Therefore, significant ketosis must be taken, appropriate treatment is necessary when ketogenesis is accelerated. The production of ketone bodies in the liver The ketone body is generated from fatty acids in the mitochondria of the liver when glycogen is depleted in the cells. First, β-adrenergic catecholamines activate lipolysis to supply fatty acids from adipose tissue during prolonged fasting or low plasma insulin levels. Adiposities release fatty acids into the bloodstream through hormone-sensitive lipase. Second, fatty acids are converted to long-chain fatty acyl CoA by fatty acyl CoA synthase. Third, CPT 1 (carnitine palmityl transferase I) catalyzes fatty acyl CoA to carnitine with the aim ...... middle of paper ...... ect on the production of ketone bodies. Ketone bodies play an important role in the body as sources of energy, especially in emergency situations due to blocked glucose supply in the body. Fatty acids are normally metabolized by the citric acid cycle after their formation to acetyl CoA, however, they are used for ketogenesis; β-oxidation occurs to generate a ketone body when glucose supply is insufficient. Ketone bodies are essential for surviving with little or no energy supply and for saving nitrogen loss from the body. Ketone bodies produced in the liver are not used in the liver, although they are used as a primary energy source in the brain, skeletal muscles, heart and kidneys. However, prolonged ketogenesis can cause ketoacidosis which can expose the body to danger causing dehydration or coma. The production of ketones therefore seems to be controlled by several hormones and enzymes..
