Deamination - GCSE Biology Definition

Deamination is a process that happens in the liver, where extra amino acids from the proteins we eat are broken down. During deamination, the amino group is removed from the amino acid, turning it into ammonia, which is then changed into a less harmful substance called urea. Urea is taken out of the blood by the kidneys and gets carried out of the body in urine. This process is important because it helps the body get rid of extra protein that it doesn’t need, and it also helps stop the build-up of toxic substances in the body.
