Deamination - Wikipedia Deamination is the removal of an amino group from a molecule [1] Enzymes that catalyse this reaction are called deaminases In the human body, deamination takes place primarily in the liver; however, it can also occur in the kidney In situations of excess protein intake, deamination is used to break down amino acids for energy
6. 4: Protein Metabolism - Medicine LibreTexts Deamination is the removal of the amine group as ammonia (NH3 NH 3), as shown below The potential problem with deamination is that too much ammonia is toxic, causing a condition known as hyperammonemia The symptoms of this condition are shown in the following figure
Deamination - Explanation, Types and Differences - Vedantu The process of removing an amino group from a molecule is called deamination, when the amino group is changed into ammonia The enzyme that stimulates this action is called deaminases Deamination principally occurs in the liver; however, glutamate is also deaminated in the kidney
Deamination Processes in Metabolism and the Nitrogen Cycle Deamination is a biochemical process involving the removal of an amino group from molecules, primarily affecting amino acids and influencing various metabolic pathways This process is significant in human metabolism and ecological systems like the nitrogen cycle
29. 9: Catabolism of Proteins- Deamination - Chemistry LibreTexts Deamination is usually accomplished by a transamination reaction in which the –NH 2 group of the amino acid is exchanged with the keto group of α-ketoglutarate, forming a new α-keto acid plus glutamate
Deamination - an overview | ScienceDirect Topics Deamination involves the loss of amino groups from DNA bases Almost all DNA bases undergo deamination in spontaneous reactions, with the exception of thymine – which does not have an amino group
The Curious Chemical Biology of Cytosine: Deamination . . . Some modifications alter coding sequences, such as deamination of cytosine by AID APOBEC enzymes to generate immunologic or virologic diversity Other modifications are critical to epigenetic control, altering gene expression or cellular identity
