Deamidation vs deamination
Did you know?
Deamination is the removal of an amino group from a molecule. Enzymes that catalyse this reaction are called deaminases. 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. The rest o… WebJul 24, 2014 · For peptides, the most common reaction of the anion radical is either deamination or deamidation.
