1,3-Cyclohexanedione is an organic compound with the formula (CH 2) 4 (CO) 2. It is one of three isomeric cyclohexanediones. It is a colorless compound that occurs naturally. It is the substrate for cyclohexanedione hydrolase. The compound exists mainly as the enol tautomer. [2]
General structure of 1,2-, 1,3-, and 1,4-dicarbonyls. In organic chemistry, a dicarbonyl is a molecule containing two carbonyl (C=O) groups.Although this term could refer to any organic compound containing two carbonyl groups, it is used more specifically to describe molecules in which both carbonyls are in close enough proximity that their reactivity is changed, such as 1,2-, 1,3-, and 1,4 ...
Cyclohexa-1,3-diene itself is rare in nature, but the cyclohexa-1,3-diene motif is fairly common. [8] One example is chorismic acid, an intermediate in the shikimic acid pathway. Of the several examples of the terpenoids and terpenes, a prominent example is phellandrene. An unusual derivative is cis-1,2-dihydrocatechol.
In enzymology, a cyclohexane-1,3-dione hydrolase (EC 3.7.1.10) is an enzyme that catalyzes the chemical reaction cyclohexane-1,3-dione + H 2 O ⇌ {\displaystyle \rightleftharpoons } 5-oxohexanoate Thus, the two substrates of this enzyme are cyclohexane-1,3-dione and H 2 O , whereas its product is 5-oxohexanoate .
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.
Dimedone is an organic compound with the formula (CH 3) 2 C(CH 2) 2 (CO) 2 (CH 2). Classified as a cyclic diketone, it is a derivative of 1,3-cyclohexanedione. It is a white solid that is soluble in water, as well as ethanol and methanol. It once was used as a reagent to test for the aldehyde functional group.
For example, an enzyme that catalyzed this reaction would be an oxidoreductase: A – + B → A + B – In this example, A is the reductant (electron donor) and B is the oxidant (electron acceptor). In biochemical reactions, the redox reactions are sometimes more difficult to see, such as this reaction from glycolysis:
