Crohn’s disease. Omega-3 fatty acids have been tested asa means to prevent relapse of Crohn’s disease. Two large,randomized, placebo-controlled studies have shown nosuch benefit from omega-3 fatty acids. Suppose you areasked to design an experiment to further study this claim.Imagine that you have collected data on Crohn’s relapsesin subjects who have used these omega-3 fatty acids and
similar subjects who have not used them and that you canmeasure incidences of relapse for these subjects. Statethe null and alternative hypotheses you would use in yourstudy.
disease. As such, a frontline treatment for Type 2 diabetes is the drug metformin, which acts indirectly
to inhibit gluconeogenesis in the liver. You are a research biochemist who would like to develop new
drugs that act to directly inhibit gluconeogenesis. You have just gained access to a library of thousands
of small molecules of unknown activity, and you would like to identify lead compounds that have specific
inhibitory activity against steps in the gluconeogenesis pathway.
(a)
into PEP in order to screen for inhibitors of enzymes specific to gluconeogenesis. Which enzymes do
you need to purify, what cofactors and allosteric effectors do they require, and which reactants do you
need to add to reconstitute the reactions for the first bypass? Which intermediates and products are
generated?
Your first approach is to reconstitute the initial set of bypass reactions that convert pyruvate

The electric charge on the functional group is determined by the relationship between its pKa and the pH of the solution. This relationship is described by the Henderson-Hasselbalch equation. 1.Histidine has three ionizable functional groups. Write the equilibrium equations for its three ion-izationsand assign the proper pKa for each ionization. Draw the structure of histidine in each ionization state.What is the net charge on the histidine molecule in each ionization state? 2.Which structure drawn in (1) corresponds to theionization state of histidine at pH 1, 4, 8, and12?Note that the ionization state can be approximated by treating each ionizable group independently. 3.What is the net charge of histidine at pH 1, 4, 8, and 12? For each pH, will histidine migrate to-ward the anode (+) or cathode (-) when placed in an electric field?arrow_forward
