WebTransamination is the most common reaction type catalyzed by PLP-dependent enzymes. It is a biologically important process by which living cells reversibly transfer the amino group from an amine (e.g., γ -aminobutyrate) or α -amino acid (e.g., aspartate) to an α-keto carboxylic acid (e.g., α -ketoglutarate). WebWhat is deamination in biology A level? This process is known as deamination: The amino group (-NH 2) of an amino acid is removed, together with an extra hydrogen atom. These combine to form ammonia (NH 3) The remaining keto acid may enter the Krebs cycle to be respired, be converted to glucose, or converted to glycogen / fat for storage. hard power on iphone
