These reactions are used in the metabolizing of proteins, carbohydrates, and lipids that will provide energy sources in the forms of adenosine triphosphate (ATP), lactic acid, and ketone bodies. Recent research shows that acetyl-CoA also plays an important regulatory role in intracellular mechanisms. It also essential for energy production when fasting or starving. See full list on biologydictionary.net Acetyl-CoA formation occurs inside or outside the cell mitochondria. As a metabolite (a substance necessary for metabolism), acetyl-CoA must be freely available. It can be produced via the catabolism (breakdown) of carbohydrates (glucose) and lipids (fatty acids). Its primary job is to transfer the carbon atoms in acetyl to other molecules. The components of acetyl co-A are, not surprisingly, acetyl and coenzyme A. An acetyl group is represented by the chemical formula CH3CO. Acetyl is produced by the breakdown of pyruvate, a derivative of carbohydrate. When pyruvate breaks down, it produces small bonded carbon molecules (C2). When they react with CoA, the combined molecule becomes acetyl-CoA. Coenzyme A is a cofactor – it assists an enzyme to provide an effect. Co-A is produced through the ingestion of vitamin B5 (pantothenic acid or pantothenate). Natural sources of this vitamin are cabbage and broccoli, whole grains, and potatoes. The chemical formula of coenzyme A is C23H38N7O17... See full list on biologydictionary.net Acetyl-CoA structure is composed of a transporting coenzyme group and an attached acetyl group. A coenzyme assists an enzyme in the breakdown of a range of biological molecules. Acetyl groups contain two carbon units and have the chemical formula C2H3O. They are composed of a methyl group (CH3) bonded via a single bond to a double-bonded carbonyl group (CO). In acetyl-CoA, the acetyl group bonds to coenzyme A. Coenzyme A is a molecule composed of beta-mercaptoethylamine, pantothenic acid (an essential vitamin), phosphate, and adenosine diphosphate (ADP). The coenzyme part is a transporter for the acetyl group. It brings the acetyl group to the right place and allows the acetyl group to transfer two carbon atoms to other substances within the citric acid cycle. See full list on biologydictionary.net Gluconeogenesis is, in simple terms, glycolysis in reverse. Where levels of glucose are low, such as in a diabetic hypoglycemic episode or during starvation or long-term fasting, the body can make glucose from non-carbohydrate sources. Acetyl-CoA plays an important regulatory role in gluconeogenesis. Most gluconeogenesis occurs in the cells of the liver; minor reactions take place in the cells of the kidneys. In gluconeogenesis, pyruvate must first be converted to phosphoenol pyruvic (PEP) acid under the influence of several enzymes. Acetyl-CoA regulates this conversion rate as it directly controls one of the many enzymes involved in this step – pyruvate carboxylase. Feedback concerning the body’s need for and supply of energy is also provided via acetyl-CoA availability. When acetyl-CoA levels are high, pyruvate is removed from the citric acid cycle and stored. The next step is the conversion of fructose to a form of glucose within the endoplasmic reticulum of the (liver) cell. Thi... See full list on biologydictionary.net Acetyl-CoA has many additional roles. These include lipid, cholesterol, and steroid synthesis that are the source of bile salts, sex hormones, aldosterone, and cortisol. These chemicals and hormones support a wide range of digestive, reproductive, and nervous system functions. Ketone bodies, a popular topic of discussion in weight-loss forums, are the result of starvation events. Oxaloacetic acid availability is important within the citric acid cycle and directly associated with acetyl-CoA availability. In the citric acid cycle, acetyl-CoA combines with oxaloacetic acid to form citric acid. When in starvation mode or during periods of hypoglycemia, glycogen reserves become depleted or cannot be used. Gluconeogenesis – glucose synthesis from fats and proteins – is necessary. If oxaloacetic acid is in short supply, acetyl CoA forms ketone bodies (ketogenesis) instead. With ketone bodies, no oxaloacetic acid is required. It is ketone bodies that can be detected in the breath of people...
