pls show complete solution

You have a trisaccharide with molecular formula C17H30O15. A diagram of the trisaccharide is shown below. Answer the questions and use the details below to draw the trisaccharide (picture attached):   If you react the trisaccharide with Ag(NH3)OH and find that a silver film develops on your reaction vessel. How would you describe the trisaccharide based on the results of the reaction? If you alkylate the trisaccharide with methyl iodide and silver oxide and hydrolyze the trisaccharide to obtain the following alkylated monosaccharides (picture attached) Determine whether each sugar was in the furanose or pyranose form. How would you draw the trisaccharide as Haworth projections, with glycosidic bond 1 as β-1,2', glycosidic bond 2 as β-1,6', and sugar C as alpha?

1. The reaction catalyzed by aldolase splits fructose-1,6-bisphosphate (F16BP) into glyceraldehyde-3-phosphate (G3P) and dihydroxyacetone phosphate (DHAP). The AG°" for the reaction is 23.8 kJ/mole. If the concentrations of G3P and DHAP are 2.5 mM and 1 mM, respectively, what concentration of F16BP is needed for the reaction to be at equilibrium in a human cell?

This is a thermodynamically unfavorable process, with ΔG°' = +13.7 kJ/mol. In a liver cell at 37°C the concentrations of both phosphate and glucose are normally maintained at about 6.2 mM each, while the  glucose-6-phosphate is around 2.1 mM . Calcaulate the Gibb's Free Energy (ΔG) of this reaction occuring in the liver

please answer question 6 and 7

The hydrolysis of pyrophosphate to orthophosphate drives biosynthetic reactions such as DNA synthesis. In Escherichia coli, a pyrophosphatase catalyzes this hydrolytic reaction. The pyrophosphatase has a mass of 120 kDa and consists of six identical subunits. A unit of activity for this enzyme, U, is the amount of enzyme that hydrolyzes 10 umol of pyrophosphate in 15 minutes. The purified enzyme has a Vnax of 2800 U per milligram of enzyme. When (S] >> KM, how many micromoles of substrate can 1 mg of enzyme hydrolyze per second? Vnax = umol -s. mg- If cach enzyme subunit has one active site, how many micromoles of active sites, or (E]r, are there in 1 mg of enzyme? (Er = umol - mg-

Glucose-1-phosphate = glucose-6-phosphate AG'o = - 7.3 kJ mol-1 Glucose-6-phosphate = fructose-6-phosphate AG'O = + 1.7 kJ mol-1 Calculate the equilibrium constant, K'eg, for the conversion of glucose-1-phosphate to fructose-6-phosphate. You can use a value of RT = 2.48 kJ mol-1.
