The following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.
In enzymology, a pyruvate synthase (EC 1.2.7.1) is an enzyme that catalyzes the interconversion of pyruvate and acetyl-CoA. It is also called pyruvate:ferredoxin oxidoreductase (PFOR). The relevant equilibrium catalysed by PFOR is: pyruvate + CoA + oxidized ferredoxin acetyl-CoA + CO 2 + reduced ferredoxin
Pyruvate, water dikinase in Neisseria meningitidis is 794 amino acids in length and has two active sites: one at at position 422 and position 752. [3] In Pyrococcus furiosus, the pyruvate, water dikinase enzyme has a subunit molecular mass of 92 kDa, and each subunit contains one calcium and one phosphorus atom. [1]
When insufficient oxygen is present, or when there is insufficient capacity for pyruvate oxidation to keep up with rapid pyruvate production during intense exertion, the pyruvate is converted to lactate − by lactate dehydrogenase), a process that absorbs these protons: [28] 2 CH 3 COCO − 2 + 2 H + + 2 NADH → 2 CH 3 CH(OH)CO − 2 + 2 NAD +
Pyruvate, the conjugate base, CH 3 COCOO −, is an intermediate in several metabolic pathways throughout the cell. Pyruvic acid can be made from glucose through glycolysis , converted back to carbohydrates (such as glucose) via gluconeogenesis , or converted to fatty acids through a reaction with acetyl-CoA .

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).
d -Glucose + 2 [NAD] + + 2 [ADP] + 2 [P] i 2 × Pyruvate 2 × + 2 [NADH] + 2 H + + 2 [ATP] + 2 H 2 O Glycolysis pathway overview The use of symbols in this equation makes it appear unbalanced with respect to oxygen atoms, hydrogen atoms, and charges. Atom balance is maintained by the two phosphate (P i) groups: Each exists in the form of a hydrogen phosphate anion, dissociating to contribute ...
In enzymology, a pyruvate oxidase (EC 1.2.3.3) is an enzyme that catalyzes the chemical reaction pyruvate + phosphate + O 2 ⇌ {\displaystyle \rightleftharpoons } acetyl phosphate + CO 2 + H 2 O 2 The 3 substrates of this enzyme are pyruvate , phosphate , and O 2 , whereas its 3 products are acetyl phosphate , CO 2 , and H 2 O 2 .
