Hydration reaction catalyst
WebNormal carbonic anhydrase has zinc at its active site. Suggest a structural reason why carbonicanhydrase synthesized with Ni²z , Fe²z, or Mn²z in place of Zn²z gives an enzyme with less catalytic efficiency. Almost all organisms contain enzymes, carbonic anhydrases, that catalyze CO 2 hydration. and HCO 3 - dehydration. Web12 feb. 2024 · Keggin heteropolyacids (HPAs) are metal–oxygen clusters with strong Bronsted acidity. The conversion of HPAs to metal salts can result in Lewis acidity, improving their performance in oxidation reactions. In this review, the main routes for the synthesis of Keggin-type heteropolyacids salts, as well their use as catalysts in …
