The following points highlight the six main processes for metabolism of carbohydrates in mammalian organism. The processes are: 1. Glycogenesis 2. Glycogenolysis 3. Glycolysis 4. Citric Acid Cycle In Mitochondri 5. Neoglucogenesis 6. Hexose Monophosphate Shunt. Carbohydrate Metabolism Process # 1. Glycogenesis: a. Glucose is first phosphorylated to glucose- 6-phosphate by the enzyme hexokinase and glucokinase in presence of the [...]
In this article we will discuss about the Oxidation of Pyruvate to Acetyl-CoA. 1. Pyruvate oxidatively decarboxylated to acetyl-CoA ("active acetate") before entering the citric acid cycle. 2. The reaction is catalysed by the multi-enzyme complex consisting of several different enzymes. This complex is known as pyruvate dehydrogenase complex. 3. Pyruvate is decarboxylated in the presence of thiamine pyrophosphate (TPP) [...]
The following points highlight the top three sources of blood glucose. The sources are: 1. From Carbohydrates of the Diet 2. From Various Glucogenic Compounds 3. From Liver Glycogen by Glycogenolysis. Blood Glucose: Source # 1. From Carbohydrates of the Diet: a. Most carbohydrates in the diet after digestion form glucose, galactose or fructose which are absorbed into the portal [...]
