The following points highlight the three main metabolic pathways for intermediary metabolism. The metabolic pathways are: 1. Carbohydrate Metabolism 2. Lipid Metabolism 3. Amino Acid Metabolism. Metabolic Pathway # 1. Carbohydrate Metabolism: a. Pyruvate and lactate are formed in the mammalian cells as a result of the oxidation of glucose by glycolysis. b. Glycolysis occurs in the cytoplasm of cells [...]
In this article we will discuss about the Interrelationship in the Metabolism of Protein, Fat and Carbohydrate: 1. Necessity for Metabolism of Protein Fat and Carbohydrate 2. Necessity of Glucose for the Brain and Erythrocytes 3. Necessity of Continual Supply of Fuel during Starvation. Necessity for Metabolism of Protein, Fat and Carbohydrate: 1. Pyruvate i s converted to acetyl-CoA which [...]
In this article we will discuss about the Metabolism of Pyrimidine Nucleotides:- 1. Biosynthesis of Pyrimidine 2. Catabolism of Pyrimidine 3. Clinical Orientation. Biosynthesis of Pyrimidine: i. The synthesis of pyrimidine ring starts with the formation of carbamoyl phosphate from glutamine, ATP and CO2 being catalyzed by carbamoyl phosphate synthetase, present in the cytosol of the cell. ii. Carbamoyl phosphate [...]
