The below mentioned article provides a short note on Proteinuria. The glomerular membrane permits only a very small amount of the normal plasma proteins. The glomerular filtrate normally contains 10 to 25 mg protein per 100 ml. This is almost completely reabsorbed by the tubular epithelial cells. 150 mg is the upper limit of normal daily protein excretion in the [...]
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 [...]
