In enzymology, a carboxylate reductase (EC 1.2.99.6) is an enzyme that catalyzes the chemical reaction. an aldehyde + acceptor + H 2 O a carboxylate + reduced acceptor. The 3 substrates of this enzyme are aldehyde, acceptor, and H 2 O, whereas its two products are carboxylate and reduced acceptor.
The polyol metabolic pathway. [6]Cells use glucose for energy.This normally occurs by phosphorylation from the enzyme hexokinase. However, if large amounts of glucose are present (as in diabetes mellitus), hexokinase becomes saturated and the excess glucose enters the polyol pathway when aldose reductase reduces it to sorbitol.
The glutathione-ascorbate cycle. Abbreviations are defined in the text. The ascorbate-glutathione cycle, sometimes Foyer-Halliwell-Asada pathway, is a metabolic pathway that detoxifies hydrogen peroxide (H 2 O 2), a reactive oxygen species that is produced as a waste product in metabolism.
Carboxylate ion Acrylate ion. In organic chemistry, a carboxylate is the conjugate base of a carboxylic acid, RCOO − (or RCO − 2). It is an anion, an ion with negative charge. Carboxylate salts are salts that have the general formula M(RCOO) n, where M is a metal and n is 1, 2,....
The Banting Memorial Lectures are a yearly series of research presentations given by an expert in diabetes. The name of the lecture series refers to Canadian physician Sir Frederick Banting, who was a seminal scientist, doctor and Nobel laureate for the co-discovery of insulin. The lectures are currently hosted by the American Diabetes Association.
The Dakin oxidation (or Dakin reaction) is an organic redox reaction in which an ortho- or para-hydroxylated phenyl aldehyde (2-hydroxybenzaldehyde or 4-hydroxybenzaldehyde) or ketone reacts with hydrogen peroxide (H 2 O 2) in base to form a benzenediol and a carboxylate. Overall, the carbonyl group is oxidised, whereas the H 2 O 2 is reduced.
The three substrates of this enzyme are (S)-1-pyrroline-5-carboxylate, NAD +, and H 2 O, whereas its three products are glutamate, NADH, and H +. This enzyme belongs to the family of oxidoreductases , specifically those acting on the CH-NH group of donors with NAD+ or NADP+ as acceptor.
Transition metal salts, especially copper compounds, [9] facilitate decarboxylation via carboxylate complex intermediates. Metals that catalyze cross-coupling reactions thus treat aryl carboxylates as an aryl anion synthon; this synthetic strategy is the decarboxylative cross-coupling reaction. [10]
