  2. Oxidative deamination - Wikipedia

    en.wikipedia.org/wiki/Oxidative_deamination

    Glutamate can then be regenerated from α-KG via the action of transaminases or aminotransferase, which catalyze the transfer of an amino group from an amino acid to an α-keto acid. In this manner, an amino acid can transfer its amine group to glutamate, after which GDH can then liberate ammonia via oxidative deamination. This is a common ...

  3. Amino acid - Wikipedia

    en.wikipedia.org/wiki/Amino_acid

    Amino acids are organic compounds that contain both amino and carboxylic acid ... The oxidation pathway starts with the removal of the amino group by a ...

  4. Deamination - Wikipedia

    en.wikipedia.org/wiki/Deamination

    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.

  5. Beta oxidation - Wikipedia

    en.wikipedia.org/wiki/Beta_oxidation

    In biochemistry and metabolism, beta oxidation (also β-oxidation) is the catabolic process by which fatty acid molecules are broken down in the cytosol in prokaryotes and in the mitochondria in eukaryotes to generate acetyl-CoA.

  6. Protein catabolism - Wikipedia

    en.wikipedia.org/wiki/Protein_catabolism

    The amino acids that are produced by protein catabolism can then be further catabolized in amino acid catabolism. Among the several degradative processes for amino acids are Deamination (removal of an amino group), transamination (transfer of amino group), decarboxylation (removal of carboxyl group), and dehydrogenation (removal of hydrogen).

  7. L-amino-acid oxidase - Wikipedia

    en.wikipedia.org/wiki/L-amino-acid_oxidase

    The three substrates of the enzymatic reaction are an L-amino acid, water, and oxygen, whereas the three products are the corresponding α-keto acid (2-oxo acid), ammonia, and hydrogen peroxide. One example of the enzyme in action occurs with the conversion L-alanine into pyruvic acid (2-oxopropanoic acid), as shown in Figure 1.

  8. Transamination - Wikipedia

    en.wikipedia.org/wiki/Transamination

    Transamination is a chemical reaction that transfers an amino group to a ketoacid to form new amino acids.This pathway is responsible for the deamination of most amino acids. This is one of the major degradation pathways which convert essential amino acids to non-essential amino acids (amino acids that can be synthesized de novo by the organism).

  9. D-amino acid oxidase - Wikipedia

    en.wikipedia.org/wiki/D-amino_acid_oxidase

    D-amino acid oxidase (DAAO; also OXDA or DAMOX) is an enzyme with the function on a molecular level to oxidize D-amino acids to the corresponding α-keto acids, producing ammonia and hydrogen peroxide. This results in a number of physiological effects in various systems, most notably the brain.
