In this article we will discuss about the Principle and Methods of Test of Urea in Urine. Principle of Test of Urea in Urine: Urea is split into ammonia and CO2 by the enzyme urease present in plants at the optimum temperature and pH. Ammonium carbonate formed as a result of ammonia and carbon dioxide shows the alkali characteristic by [...]
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 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 [...]
