WebApr 10, 2024 · In the transamination biochemical process, an amino group is transferred to a keto group; in the biochemical deamination process, excess protein breakdown in the liver releases ammonia. Conclusion In case of excess protein intake, deamination breaks down the amino acid into ammonia for energy. WebPyridoxal 5'-phosphate enzymes are ubiquitous in the nitrogen metabolism of all organisms. They catalyze a wide variety of reactions including racemization, transamination, decarboxylation, elimination, retro-aldol cleavage, Claisen condensation, and others on substrates containing an amino group, most commonly α-amino acids.
