Short Notes on Aminotransferases | Protein Metabolism

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 [...]

Processes of Decarboxylation | Protein Metabolism

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 [...]

Mechanisms of Amino Acids (13 Mechanisms ) | Protein Metabolism

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 [...]
