Oxalate occurs in many plants, where it is synthesized by the incomplete oxidation of saccharides. Several plant foods such as the root and/or leaves of spinach, rhubarb, and buckwheat are high in oxalic acid and can contribute to the formation of kidney stones in some individuals. Other oxalate-rich plants include fat hen ("lamb's quarters ...
Citrate has been shown to inhibit the oxidation of L-malate when there are low levels of L-malate and NAD +. However, in the presence of high levels of malate and NAD +, citrate can stimulate the production of oxaloacetate. Although malate dehydrogenase is typically considered a reversible enzyme, it is believed that there is an allosteric ...
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.
Oxalic acid is an organic acid with the systematic name ethanedioic acid and chemical formula HO−C(=O)−C(=O)−OH, also written as (COOH) 2 or (CO 2 H) 2 or H 2 C 2 O 4.It is the simplest dicarboxylic acid.
In enzymology, an oxaloacetase (EC 3.7.1.1) is an enzyme that catalyzes the chemical reaction: [1] oxaloacetate + H 2 O ⇌ {\displaystyle \rightleftharpoons } oxalate + acetate Thus, the two substrates of this enzyme are oxaloacetate and H 2 O , whereas its two products are oxalate and acetate .
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.
In enzymology, an oxalate oxidase (EC 1.2.3.4) is an oxalate degrading enzyme that catalyzes the chemical reaction: oxalate + O 2 + 2 H + ⇌ {\displaystyle \rightleftharpoons } 2 CO 2 + 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 .
Glyoxylate is both a substrate and inductor of sulfate anion transporter-1 (sat-1), a gene responsible for oxalate transportation, allowing it to increase sat-1 mRNA expression and as a result oxalate efflux from the cell. The increased oxalate release allows the buildup of calcium oxalate in the urine, and thus the eventual formation of kidney ...
