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 [...]
The following points highlight the top thirteen mechanisms of amino acids in body. 1. The amino acids are required for the synthesis of protein. 2. These are utilized for the synthesis of methionine which is methyl donor. This methyl donor is required for the synthesis of choline, betaine, creatine and epinephrine. Methionine can also be converted into cystine when this [...]
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 [...]
