Speciation diagram for a 10-millimolar solution of citric acid. The violet curve corresponds to the trisodium citrate. As a conjugate base of a weak acid, citrate can perform as a buffering agent or acidity regulator, resisting changes in pH. It is used to control acidity in some substances, such as gelatin desserts. It can be found in the milk ...
Citrate synthase ( E.C. 2.3.3.1 (previously 4.1.3.7)) is an enzyme that exists in nearly all living cells. It functions as a pace-making enzyme in the first step of the citric acid cycle (or Krebs cycle ). [ 5] Citrate synthase is located within eukaryotic cells in the mitochondrial matrix, but is encoded by nuclear DNA rather than mitochondrial.
Aconitase (aconitate hydratase; EC 4.2.1.3) is an enzyme that catalyses the stereo-specific isomerization of citrate to isocitrate via cis - aconitate in the tricarboxylic acid cycle, a non- redox -active process. [ 3][ 4][ 5] Citric acid. Aconitic acid. Isocitric acid.
Citric acid is an excellent chelating agent, binding metals by making them soluble. It is used to remove and discourage the buildup of limescale from boilers and evaporators. [ 15] It can be used to treat water, which makes it useful in improving the effectiveness of soaps and laundry detergents.
Calcium citrate is the calcium salt of citric acid. It is commonly used as a food additive ( E333 ), usually as a preservative, but sometimes for flavor. In this sense, it is similar to sodium citrate. Calcium citrate is also found in some dietary calcium supplements (e.g. Citracal or Caltrate ).
Isocitrate dehydrogenase ( IDH) ( EC 1.1.1.42) and ( EC 1.1.1.41) is an enzyme that catalyzes the oxidative decarboxylation of isocitrate, producing alpha-ketoglutarate (α-ketoglutarate) and CO 2. This is a two-step process, which involves oxidation of isocitrate (a secondary alcohol) to oxalosuccinate (a ketone ), followed by the ...
In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical reaction occurs. [ 1] A chemical mechanism is a theoretical conjecture that tries to describe in detail what takes place at each stage of an overall chemical reaction. The detailed steps of a reaction are not observable in most cases.
3. Cosm insists this is not a theater "We're allergic to the term theater," Poolman says. Cosm's creators want the spaces to feel social. That's why they also sell a low-priced general admission ...
