The below mentioned article provides a note on protein metabolism. Notion of Nitrogen Balance: If one determines, on the one hand, the quantity of nitrogen ingested by an animal and on the other hand the quantity excreted in urine and faeces, one may observe three situations: i. The nitrogen excreted is less than the nitrogen ingested, i.e. there is retention [...]
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 [...]
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 [...]
