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 [...]
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 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 [...]
