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 three main processes for biosynthesis of urea. The processes are: 1. Transamination 2. Oxidative Deamination 3. Ammonia Formation and Transport. Process # 1. Transamination: a. Transamination involves inter-conversion of a pair of α-amino acids and a pair of α- keto acids and is catalysed by transaminases or aminotransferases. b. Pyridoxal phosphate (B6 PO4) is the [...]
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 [...]
