Vitamins and Coenzymes

A class of organic compounds needed in the human body for normal activities is known as vitamins. They are characterized into two parts depending upon their solubility in water. They can act as coenzymes, cofactors, or prosthetic groups for enzymes.

Question

please please help me to answer it >>> i have an exam

Human xanthine oxidase catalyzes the oxidation of hypoxanthine to xanthine and can further
catalyze 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 the
production of uric acid. You are a biochemist and just discovered a chemical that can inhibit
the activity of the human xanthine oxidase. When analyzing its mode of inhibition, you found
that the enzyme inhibitor complex requires 450 J.mol
-1 to dissociate and that it displays
kinetics somehow similar to noncompetitive inhibition. You sent your inhibitor to the ministry
of health for approval as a medication for gout. Based on the data provided, are they going to
authorize it as a medication or not? Explain?

Expert Solution

Step 1

Human xanthine oxidase is an enzyme that catalyses the oxidation of hypoxanthine to xanthine and further catalyses the oxidation of xanthine to uric acid. It is the enzyme responsible for hyperuricemia and gout.

The catalytic efficiency of many enzymes depends on pH. Chymotrypsinshows a maximum value of kcat/KM at pH 8. Detailed analysis shows thatkcat increases rapidly between pH 6 and 7 and remains constant at higherpH. KM also increases rapidly between pH 8 and 10. Suggest explanationsfor these observations.

The catalytic efficiency of many enzymes depends on pH. Chymotrypsin, which has a well-known catalytic mechanism, shows a maximum value of kcat/Km at pH 8.0. A) Draw a pH curve of chymotrypsin activity over the pH range of 5 to 10 and briefly explain the rationale within the context of catalysis for your depiction. In particular, note how kcat and Km may change over this pH range. B) Enzymes of the a-amylase family catalyze a reaction by forming a covalent intermediate analogous to chymotrypsin, but to a conserved aspartate residue. Illustrate a catalytic mechanism containing a tetrahedral intermediate for a glycogen debranching enzyme based upon its potential membership in the a-amylase family.

3) The enzyme aldolase catalyzes the conversion of fructose-1,6-diphosphate (FDP)to dihydroxyacetone phosphate (DHAP) and glyceraldehide-3-phosphate (G3P). Thereaction isFDP ⇄ DHAP + G3P , ∆rG0(298.15 K) = 23.8 kJ mol−1In red blood cells the concentration of these species are [FDP] = 35 µM, [DHAP] =130 µM, and [G3P] = 15 µM. (Remember that 1.0 µM = 1.0 × 10−6 mol L−1. Thestandard state for reactions in solution can be taken as c0 = 1.0 mol L−1).Calculate ∆rG in a red blood cell at 25 0C. Will the reaction occur spontaneouslyin the cell at this temperature?
The hydrolysis of a biological thioester to the corresponding carboxyl-ate is often more complex than the overall result might suggest. The conversion of succinyl CoA to succinate in the citric acid cycle, for instance, occurs by initial formation of an acyl phosphate, followed by reaction with guanosine diphosphate (GDP, a relative of adenosine diphosphate [ADP]) to give succinate and guanosine triphosphate (GTP, a relative of ATP). Suggest mechanisms for both steps.
Calculate the value of the denaturation constant kd for a given enzyme, using the equation provided from the text and lecture of kd = Ad e(-Ed/RT) where Ad = 6.1 x 1047 and Ed = 69 kcal/g mole. Then, prepare a plot of per cent enzyme maximal activity vs temperature using an Ea of 23 kcal/gmole, and an enzyme concentration E0 of unity. Note that the y-axis of this plot is a per cent value, so the value of A in the Arrhenius equation does not need to be known in this case. On the denaturation side of the curve, use 5 minutes as the constant exposure time. Use a temperature range of 20 to 50⁰C.
The enzyme d-amino acid oxidase has avery high turnover number because the d-amino acids are potentially toxic.

Which of these amino acids are the preferred substrates for the enzyme?
