Short Notes on Aminotransferases | Protein Metabolism

The below mentioned article provides a short note on Aminotransferases. Aminotransferases catalyse the transfer of amino group from an amino acid to a keto acid—a new amino and keto acid are formed in this process. Clinically, the two most important aminotrans­ferases are: Glutamic oxaloacetic transaminase (GOT), now designated aspartate aminotransferase and glutamic pyruvic transaminase (GPT), now des­ignated alanine aminotransferase. These [...]

Processes of Decarboxylation | Protein Metabolism

The following points highlight the four main processes of Decarboxylation. The processes are: 1. Tyramine 2. Tryptamine 3. Histamine 4. GABA (γ-aminobutyric acid). Decarboxylation Process # 1. Tyramine: i. Tyramine is formed from tyrosine by ty­rosine decarboxylation causing elevation of blood pressure. ii. This occurs in the gut by bacterial action. iii. The reaction takes place also in the kid­ney [...]

Reactions of Urea Cycle | Protein Metabolism

The below mentioned article provides a short note on the Reactions of Urea Cycle. Carbamoyl phosphate is formed by the condensation of one mol of phosphate (derived from ATP) being catalyzed by the enzyme carbamoyl phosphate synthetase which is present in liver mitochondria of all ureotelic organisms including humans. In addition to magnesium ion (Mg++), N-acetyl-glutamate (a dicarboxylic acid) is [...]
