Oxalate (systematic IUPAC name: ethanedioate) is an anion with the chemical formula C 2 O 2− 4. This dianion is colorless. It occurs naturally, including in some foods. It forms a variety of salts, for example sodium oxalate (Na 2 C 2 O 4), and several esters such as dimethyl oxalate ((CH 3) 2 C 2 O 4). It is a conjugate base of oxalic acid.
In enzymology, a malate oxidase (EC 1.1.3.3) is an enzyme that catalyzes the chemical reaction (S)-malate + O 2 oxaloacetate + H 2 O 2. Thus, the two substrates of this enzyme are (S)-malate and O 2, whereas its two products are oxaloacetate and H 2 O 2.
The 3 substrates of this enzyme are oxalate, O 2, and H +, whereas its two products are CO 2 and H 2 O 2. This enzyme belongs to the family of oxidoreductases, specifically those acting on the aldehyde or oxo group of donor with oxygen as acceptor. The systematic name of this enzyme class is oxalate:oxygen oxidoreductase.
2 is no longer zero as with the standard hydrogen electrode (SHE) at 1 M H + (pH = 0) in classical electrochemistry, but that = versus the standard hydrogen electrode (SHE). [2] The same also applies for the reduction potential of oxygen: O 2 + 4 H + + 4 e − ⇌ 2 H 2 O
One is found in the mitochondrial matrix, participating as a key enzyme in the citric acid cycle that catalyzes the oxidation of malate. The other is found in the cytoplasm , assisting the malate-aspartate shuttle with exchanging reducing equivalents so that malate can pass through the mitochondrial membrane to be transformed into oxaloacetate ...
Oxalate oxidase （Enzyme Commission number EC 1.2.3.4 [2] ）occurs mainly in plants. It can degrade oxalic acid into carbon dioxide and hydrogen peroxide. [3]Oxalate decarboxylase (OXDC，EC 4.1.1.2) is a kind of oxalate degrading enzyme containing Mn 2+, [4] found mainly in fungi or some bacteria.
Oxaloacetic acid (also known as oxalacetic acid or OAA) is a crystalline organic compound with the chemical formula HO 2 CC(O)CH 2 CO 2 H. Oxaloacetic acid, in the form of its conjugate base oxaloacetate, is a metabolic intermediate in many processes that occur in animals.
The international pictogram for oxidizing chemicals. Dangerous goods label for oxidizing agents. An oxidizing agent (also known as an oxidant, oxidizer, electron recipient, or electron acceptor) is a substance in a redox chemical reaction that gains or "accepts"/"receives" an electron from a reducing agent (called the reductant, reducer, or electron donor).
