Detailed explanation-1: -In oxidative deamination, amino groups are removed from amino acids, resulting in the formation of corresponding keto acids and ammonia.

Detailed explanation-2: -During oxidative deamination, an amino acid is converted into the corresponding keto acid by the removal of the amine functional group as ammonia and the amine functional group is replaced by the ketone group. The ammonia eventually goes into the urea cycle.

Detailed explanation-3: -The amino group of alanine is attached to -ketoglutarate through transamination into glutamate.

Detailed explanation-4: -There are two types of deamination, non oxidative and oxidative deamination. This process breaks down the excess protein from the diet by removing the amino group from amino acids. Both deamination reactions are catalyzed by enzymes. Additionally, both reactions produce ammonia corresponding to a-keto acids.

Detailed explanation-5: -Three amino acids can be deaminated directly: glutamate (catalysed by glutamate dehydrogenase), glycine (catalysed by glycine oxidase) and serine (catalysed by serine dehydrogenase).
