CHEM 313 Chapter Notes -Anomer, Magnesium Oxide, Stereochemistry
Document Summary
Chem 313 problem set #6 2014: hydrolysis of triphosphates provides the energy for life. Compare these factors with the hydrolysis of acetic anhydride. O p: phosphoric acid (h3po4) is triprotic, meaning that it has three acidic hydrogens. O available to donate, with pka values of 2. 1, 7. 2, and 12. 3, respectively. Has half, less than half or more than half of the phosphoric acid species in solution donated two protons: give the intermediate a and b as well as the mechanism to get to each of them. Don"t worry about the stereochemistry at the anomeric carbon and the pentavalente phosphate intermediate. Co2: describe the mechanism that allows the regeneration of atp from adp with pyruvate kinase. Here, we will cheat and assume that the reaction is stepwise. Thus, the magnesium oxide doesn"t end up like that in the real enzyme, but here, it is only to help you finding the mechanism of the last step.
