Which of the following organs is associated with deamination of proteins?

The organ that is associated with deamination of proteins is the liver. Deamination is the process of removing the amino group (-NH2) from amino acids, which is the first step in the breakdown of proteins. The liver contains a group of enzymes called transaminases, which are responsible for the deamination of amino acids. Once the amino group is removed, it is converted to ammonia and then to urea, which is eliminated from the body in urine. Therefore, the liver plays a crucial role in protein metabolism and waste elimination.
