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 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 [...]
