please please help me to answer it >>> i have an exam Human xanthine oxidase catalyzes the oxidation of hypoxanthine to xanthine and can furthercatalyze the oxidation of xanthine to uric acid. For the treatment of hyperuricemia and gout,several medications are used to inhibit the activity of xanthine oxidase and reduce theproduction of uric acid. You are a biochemist and just discovered a chemical that can inhibitthe activity of the human xanthine oxidase. When analyzing its mode of inhibition, you foundthat the enzyme inhibitor complex requires 450 J.mol-1 to dissociate and that it displayskinetics somehow similar to noncompetitive inhibition. You sent your inhibitor to the ministryof health for approval as a medication for gout. Based on the data provided, are they going toauthorize it as a medication or not? Explain?
The disaccharide lactulose consists of a d-galactopyranose subunit and a d-fructofuranose subunit joined by a β-1,4-glycosidic linkage. After treatmentof lactulose with 1. excess CH3I/Ag2O, 2. HCl/H2O, the d-galactopyranose subunit was found to have one nonmethylated OH group, whereas thed-fructofuranose subunit had two. Draw the structure of α-lactulose.

Answer for 23.29 a) Since the energy required for the forward reaction is given as 3.9 Kcal/mol hence for the reverse reaction energy will be -ve of forward reaction Hence the energy change of reverse reaction is -3.9 Kcal/mol b) The ATP hydrolysis reaction is as shown below ATP + H20 -----> ADP + Pi + Energy where energy given in qu = 7.3 Kcal/mol Hence adding the above reaction with the given reaction we get the coupled reaction as fructose 6 phosphate + ATP + HPO4- ----> fuctose-1,6-biphosphate + Pi c.) The energy change of the above coupled reaction = energy change of reaction 1 + energy change of reaction 2 => energy change of the above coupled reaction = 3.9 + (-7.3) = -3.4 Kcal/mol Since the net energy change of the couple reaction is -ve And since the reactions with -ve energy change is spontaneous Hence by coupling the reaction, we are making the phosphorylation reaction spontaneous I need help interpreting it in 29.30 (image attached).
