[ [ Ketone Bodies ] The three water-soluble molecules, acetoacetic acid, beta-hydroxybutyric acid and acetone, that are produced during the metabolic state of ketosis. Ketone bodies are an important source of energy for the brain and heart during fasting or strenuous exercise. They are converted into acetyl-CoA which then enter the Krebs_cycle to produce ATP. The brain also converts acetyl-CoA into More ]
The three water-soluble molecules, [ Acetoacetic acid ] One of the three ketone bodies produced during the metabolic state of ketosis or ketoacidosis. More, [ Beta-hydroxybutyric acid, β-Hydroxybutyric acid, 3-hydroxybutyric acid, D-3-hydroxybutyrate ] Although not a ketone itself, it is one of the three chemicals, or ketone bodies, produced during the metabolic state of ketosis or ketoacidosis. Beta-hydroxybutyric acid is the first of these to be produced in the fasting state. Beta-hydroxybutyric acid levels increase with exercise, calorie restriction, fasting, and ketogenic diets. It More and [ Acetone ] An organic compound with a pungent floral or fruity odour. It is one of the three ketone bodies produced by the liver during the metabolic state of ketosis. Acetone is water-soluble, volatile and highly flammable. It has many commercial applications as an organic solvent and synthetic reagent. It is the active ingredient in nail polish remover and More, that are produced during the metabolic state of [ Ketosis ] A metabolic state of ketogenesis, where the liver produces ketone bodies as a supplementary energy source. It is characterised by blood concentrations of ketone bodies over 0.5 millimolar, and low levels of insulin and blood glucose, usually triggered by fasting or a dietary shortage of carbohydrates. Compare: Ketoacidosis More.
Ketone bodies are an important source of energy for the brain and heart during fasting or strenuous exercise. They are converted into [ Acetyl_Co-Enzyme_A, Acetyl-CoA ] A product of fatty acid oxidation and of the breakdown of carbohydrates through glycolysis. Along with pyruvic acid, an important constituent of the Krebs Cycle, which drives cellular energy production. More which then enter the [ Krebs_Cycle, Citric_Acid_Cycle, Tricarboxylic_Acid_Cycle, TCA_Cycle ] The metabolic pathway taking place in the mitochondria of all aerobic organisms that produces ATP through the oxidation of acetyl-CoA from carbohydrates, fatty acids and amino acids. Named after the biochemist, Sir Hans A. Krebs. More to produce [ Adenosine_Triphosphate, ATP ] A nucleoside triphosphate used in cells as a coenzyme in energy metabolism. ATP carries energy to where it is needed to fuel metabolic processes and is often referred to as the "molecular unit of currency". More. The brain also converts acetyl-CoA into long chain [ Fatty_Acid ] A carboxylic acid with a hydrocarbon chain, usually derived from triglycerides or phospholipids. Fats, oils and esters are comprised of fatty acids. In the body, fatty acids function as the building blocks of cell membranes and signalling molecules. As fuel, they have a high-energy yield (9 kcal/gram) and are the primary means of energy storage in the More.
Acetoacetic acid, and beta-hydroxybutyric acid are produced from fatty acids and the [ Deamination ] The removal of an amino group from a molecule such as an amino acid, catalysed by deaminases. Deamination may be used to break down excess amino acids into carbohydrates or ketone bodies. More of [ Ketogenic Diet ] A dietary regimen in which the carbohydrate intake is severely limited, resulting in the metabolic state of ketosis. The ketogenic diet is sometimes prescribed as a means of controlling the frequency and severity of epileptic seizures. More [ Amino acid ] A simple organic compound containing containing both an amine (-NH2) and a carboxyl (-COOH) functional group, along with a side-chain (R group), which is specific to each amino acid. Amino acids are the building blocks of proteins and perform critical roles in biosynthesis and neurotransmitter transport. There are over 500 amino acids known but only 20 More. Acetone is a degradation breakdown product of acetoacetic acid.
Surplus ketone bodies are excreted via the kidneys.
