The process of removing an amino group from a compound, often related to the breakdown of amino acids in the body.
Deamination is an important step in the metabolism of proteins.
Deamination is formed from "de-" (meaning removal or reversal) and "amino" (from the Greek "aminon", meaning nitrogen-containing group) and "-ation" (meaning the process of). The word refers to the process of removing an amino group from a molecule.
Think of 'removal' ('de-') of an 'amino group' ('amino') — that's what deamination means, the process of removing an amino group.
