What is the deamination of protein?

Deamination is the bodily process in which amino groups are removed from excess proteins. This happens most often in the liver, though it also occurs in the kidneys. Deamination allows the system to convert excess amino acids into usable resources such as hydrogen and carbon. The process also plays a vital role in removing nitrogen waste from the body. Amino groups discarded as a result of the process are converted into ammonia, which is later expelled from the body through urination.
