deaminointia
Deaminointia is a Finnish term that translates to deamination in English. Deamination is a chemical reaction in biochemistry that involves the removal of an amino group (-NH2) from a molecule. This process is crucial in the metabolism of amino acids and nucleotides. In the context of amino acid metabolism, deamination removes the amino group from an amino acid, converting it into a keto acid and ammonia. This ammonia is then typically converted to urea in the liver and excreted by the kidneys. Deamination also occurs in the breakdown of nucleic acids, where it removes amino groups from the nitrogenous bases adenine and guanine, leading to the formation of hypoxanthine and xanthine, respectively. These reactions are catalyzed by enzymes called deaminases. The products of deamination can then enter various metabolic pathways, such as the citric acid cycle for energy production or be used in the synthesis of other molecules. Understanding deamination is fundamental to comprehending metabolic pathways and the processing of biological molecules within living organisms.
