Deamination...... (:

Deamination is a process that occurs in the liver that removes the nitrogen-containing portions (-NH2 groups) from the amino acids. These -NH2 groups subsequently react to form a waste called urea. The liver therefore produces urea from amino groups formed by deamination of amino acids. The blood carries urea to the kidneys, where it is excreted in urine.
