Detailed explanation-1: -In the human body, deamination takes place primarily in the liver, however it can also occur in the kidney. In situations of excess protein intake, deamination is used to break down amino acids for energy. The amino group is removed from the amino acid and converted to ammonia.
Detailed explanation-2: -In the human body, deamination takes place in the liver. It is the process by which amino acids are broken down. The amino group is removed from the amino acid and converted to ammonia. The rest of the amino acid is made up of mostly carbon and hydrogen, and is recycled or oxidized for energy.
Detailed explanation-3: -Much of the oxidative deamination occurring in cells involves the amino acid glutamate, which can be oxidatively deaminated by the enzyme glutamate dehydrogenase (GDH), using NAD or NADP as a coenzyme. This reaction generates -ketoglutarate (-KG) and ammonia.
Detailed explanation-4: -In oxidative deamination, amino groups are removed from amino acids, resulting in the formation of corresponding keto acids and ammonia.
