Difference Between Oxidative and Nonoxidative Deamination Compare the Difference Between
Glutamate is the only amino acid that undergoes oxidative deamination to a significant extent to liberate free NH3 for urea synthesis. All amino acids

Figure 6.4.1 6.4. 1: Generic transamination reaction where the top keto acid is converted to an amino acid, while the bottom amino acid is converted to a keto acid 1. Keto acids (also known as carbon skeletons) are what remains after amino acids have had their nitrogen group removed by deamination or transamination.

Figure 7.5.15 7.5. 15. Depurination of guanines (or adenines) is a common DNA lesion. Three of the four DNA bases, adenine, guanine, and cytosine, contain amine groups that can be lost in a variety of pH and temperature-dependent reactions that convert the bases to hypoxanthine, xanthine, and uracil, respectively.

Oxidative deamination. Oxidative deamination reaction replaces −NH+3 − NH 3 + with a C=O C = O, producing an α α -keto acid and an ammonium ( NH+4 NH 4 +) ion, as shown in reaction 2 in Figure 9.7.1 9.7. 1. This is an oxidation reaction that is coupled with the reduction of NAD+ NAD + to NADH NADH.

3.1.2 Non-oxidative Deamination. It is the deamination of amino acids in the absence of molecular oxygen in cells. Non-oxidative deamination takes place by substrate-specific enzymes. Depending on types of amino acids, non-oxidative deamination has the following three types:
What is the Difference Between Oxidative and Nonoxidative Deamination
Non oxidative deamination Transamination Most amino acids are deaminated by transamination reaction catalysed by aminotransferases or transaminases. The -amino group present in an amino acid is transferred to an -keto acid to yield a new amino acid and the -keto acid of the original amino acid.

Nonoxidative deamination is a type of deamination reaction in which the removal of the amine group occurs without proceeding through an oxidation reaction. However, this type of deamination reactions liberates ammonia, producing the corresponding α-keto acids.
General Reactions involved in amino acid metabolism
It may be accomplished oxidatively or nonoxidatively. Oxidative deamination is stereospecific and is catalyzed by L- or D-amino acid oxidase. The initial step is removal of two hydrogen atoms by the flavin coenzyme, with formation of an unstable α-amino acid intermediate.

Oxidative deamination is a form of deamination that generates α-keto acids and other oxidized products from amine-containing compounds, and occurs primarily in the liver. [1]

Oxidative Deamination. In the breakdown of amino acids for energy, the final acceptor of the α-amino group is α-ketoglutarate, forming glutamate. Glutamate can then undergooxidative deamination, in which it loses its amino group as an ammonium (NH 4 +) ion and is oxidized back to α-ketoglutarate (ready to accept another amino group):

Deamination may be either oxidative or non- oxidative. Urea Cycle: ADVERTISEMENTS: Urea is the end product of protein metabolism (amino acid metabolism). The nitrogen of amino acids converted to ammonia is toxic to the body. It is converted to urea and detoxified. As such, urea accounts for 80-90% of the nitrogen containing substances excreted.
