Detailed explanation-1: -Whereas in deamination, an amino group is removed from an amino acid or other compounds. In the process of deamination, excess protein is converted into ammonia, then to urea; on the other hand, in transamination, the synthesis of nonessential amino acids takes place.
Detailed explanation-2: -Typically in humans, deamination occurs when an excess in protein is consumed, resulting in the removal of an amine group, which is then converted into ammonia and expelled via urination. This deamination process allows the body to convert excess amino acids into usable by-products.
Detailed explanation-3: -Deamination is the removal of an amine group from a molecule. 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.
Detailed explanation-4: -Deamination of amino acids results in the production of ammonium (NH4+). Ammonium is an extremely toxic base and its accumulation in the body would quickly be fatal. However, the liver contains a system of carrier molecules and enzymes which quickly converts the ammonia (and carbon dioxide) into urea.
Detailed explanation-5: -Transamination is the major process for removing nitrogen from amino acids.
