In enzymology, a formaldehyde dehydrogenase (EC 1.2.1.46) is an enzyme that catalyzes the chemical reaction formaldehyde + NAD + + H 2 O ⇌ {\displaystyle \rightleftharpoons } formate + NADH + H + The 3 substrates of this enzyme are formaldehyde , NAD + , and H 2 O , whereas its 3 products are formate , NADH , and H + .
Formate dehydrogenases are a set of enzymes that catalyse the oxidation of formate to carbon dioxide, donating the electrons to a second substrate, such as NAD + in formate:NAD+ oxidoreductase (EC 1.17.1.9) or to a cytochrome in formate:ferricytochrome-b1 oxidoreductase (EC 1.2.2.1). [1]
Oxidoreductases, enzymes that catalyze oxidation-reduction reactions, constitute Class EC 1 of the IUBMB classification of enzyme-catalyzed reactions. [2] Any of these may be called dehydrogenases, especially those in which NAD + is the electron acceptor (oxidant), but reductase is also used when the physiological emphasis on reduction of the substrate, and oxidase is used only when O 2 is the ...
In enzymology, a mycothiol-dependent formaldehyde dehydrogenase (EC 1.1.1.306) is an enzyme that catalyzes the chemical reaction formaldehyde + mycothiol + NAD + ⇌ {\displaystyle \rightleftharpoons } S-formylmycothiol + NADH + 2 H +
The enzyme is inhibited competitively by methoxyacetic acid, which has a Ki of 0.26 mM [9] The exact mechanism of sarcosine dehydrogenase is not available. However, according to the overall net reaction discussed in Honova.E, et al. paper: Sarcosine + H 2 O + O 2 → glycine + formaldehyde + H 2 O 2 [10]
In organic chemistry, the Mannich reaction is a three-component organic reaction that involves the amino alkylation of an acidic proton next to a carbonyl (C=O) functional group by formaldehyde (H−CHO) and a primary or secondary amine (−NH 2) or ammonia (NH 3). [1] The final product is a β-amino-carbonyl compound also known as a Mannich base.
The Eschweiler–Clarke reaction (also called the Eschweiler–Clarke methylation) is a chemical reaction whereby a primary (or secondary) amine is methylated using excess formic acid and formaldehyde. [1] [2] Reductive amination reactions such as this one will not produce quaternary ammonium salts, but instead will stop at the tertiary amine ...
Delta-aminolevulinic acid dehydratase (ADA-D) is found in blood and is involved in the production of the heme group of globins. [5] People exposed to lead will have a decrease in ADA-D activity. [6] Serine dehydratase is mostly found in the liver and catalyzes the reaction of turning serine into pyruvate and ammonia. In a diet of increased ...
