The following points highlight the two main levels of metabolic pathways for intermediary metabolism. The levels are: 1. Intermediary Metabolism at the Tissue and Organ Level 2. Intermediary Metabolism at the Subcellular Level. Level # 1. Intermediary Metabolism at the Tissue and Organ Level: a. Amino acids formed from the digestion of dietary protein and glucose formed from the digestion [...]
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 [...]
