Phosphite hydrolysis
WebFeb 1, 2024 · Our results clearly show that the major physiological alterations resulting from expression of the phosphoketolase in S. cerevisiae are effects related to the native hydrolysis of the phosphoketolase product acetyl-phosphate to acetate. This forces the cell to spend energy on maintaining intracellular ion balances, in particular at low pH, as ... WebThe predominant phytate hydrolysis products were inositol phosphates, typically formed by plant phytases. For the phytase inactivated diet, comparable very low phytase activity and almost no phytate degradation in the stomach were determined. In the small intestine and colon, high activity of alkaline phosphatases and low activity of phytases ...

In organic chemistry, a phosphite ester or organophosphite usually refers to an organophosphorous compound with the formula P(OR)3. They can be considered as esters of an unobserved tautomer phosphorous acid, H3PO3, with the simplest example being trimethylphosphite, P(OCH3)3. Some phosphites … See more From PCl3 Phosphite esters are typically prepared by treating phosphorus trichloride with an alcohol. For alkyl alcohols the displaced chloride ion can attack the phosphite, causing dealkylation … See more Diorganophosphites are derivatives of phosphorus(V) and can be viewed as the di-esters of phosphorous acid ((HO)2P(O)H). They exhibit tautomerism, however, the equilibrium overwhelmingly favours the right-hand (phosphonate-like) form: See more Reactions Phosphites are oxidized to phosphate esters: P(OR)3 + [O] → OP(OR)3 This reaction … See more • Phosphinite P(OR)R2 • Phosphonite P(OR)2R • Ortho ester CH(OR)3 • Borate ester B(OR)3 See more WebMay 11, 2024 · Phosphinic and phosphonic acids are useful intermediates and biologically active compounds which may be prepared from their esters, phosphinates and phosphonates, respectively, by hydrolysis or dealkylation. The hydrolysis may take place both under acidic and basic conditions, but the C-O bond may also be cleaved by …
WebPhosphites are efficient decomposers of hydroperoxides that are formed during the autooxidation of polymers. Phosphites are especially used in melt processing where they are added in blends with hindered phenolic antioxidants. Such combinations are more effective than hindered phenol alone.
