Adenosine is used as an intravenous medication for some cardiac arrhythmias. Adenosyl (abbreviated Ado or 5'-dAdo ) is the chemical group formed by removal of the 5′-hydroxy (OH) group. It is found in adenosylcobalamin (an active form of vitamin B12 [ 1 ] ) and as a radical in the radical SAM enzymes.
Transgenetically expressed, ADO appears to be dependent on ferredoxin-ferredoxin reductase to deliver reducing equivalents, but the endogenous reducing system is not known. [2] Further, oxygen-independent aldehyde deformylation has also been observed. [6] H 2 O 2 is an inhibitor of cADO, and an ADO-catalase fusion protein exhibits improved ...
Adenosine monophosphate (AMP), also known as 5'-adenylic acid, is a nucleotide.AMP consists of a phosphate group, the sugar ribose, and the nucleobase adenine.It is an ester of phosphoric acid and the nucleoside adenosine. [1]
The radical intermediates generated by these enzymes perform a wide variety of unusual chemical reactions. Examples of radical SAM enzymes include spore photoproduct lyase , activases of pyruvate formate lyase and anaerobic sulfatases, lysine 2,3-aminomutase , and various enzymes of cofactor biosynthesis, peptide modification, metalloprotein ...
2,3-Dichloro-5,6-dicyano-1,4-benzoquinone (or DDQ) is the chemical reagent with formula C 6 Cl 2 (CN) 2 O 2. This oxidant is useful for the dehydrogenation of alcohols, [3] phenols, [4] and steroid ketones. [5] DDQ decomposes in water, but is stable in aqueous mineral acid. [6]
Adenosine kinase (AdK; EC 2.7.1.20) is an enzyme that catalyzes the transfer of gamma-phosphate from Adenosine triphosphate to adenosine (Ado) leading to formation of Adenosine monophosphate . In addition to its well-studied role in controlling the cellular concentration of Ado, AdK also plays an important role in the maintenance of methylation ...
strong base used in organic chemistry for the deprotonation of weakly acidic compounds Manganese dioxide: used as a pigment and as a precursor to other manganese compounds; used as a reagent in organic synthesis for the oxidation of allylic alcohols Meta-Chloroperoxybenzoic acid: used as an oxidant in organic synthesis Methyl tert-butyl ether
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
