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 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 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 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.
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 final step in the reduction of carboxylic acids and esters is hydrolysis of the aluminium alcoxide. [8] Esters (and amides) are more easily reduced than the parent carboxylic acids. Their reduction affords alcohols and amines, respectively. [9] The idealized equation for the reduction of an ester by lithium aluminium hydride is:
The 3 substrates of this enzyme are L-proline, NAD +, and NADP +, whereas its 4 products are 1-pyrroline-2-carboxylate, NADH, NADPH, 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.
