The building block of pectic substances is A) sucrose B) glucose C) fructose D) galactose E) cellulose
Draw the structures of glucose, fructose, sucrose, starch, and cellulose (your structures must show the correct stereochemistry; for starch and cellulose draw at least two repeating units). Comment on the structural differences between starch and cellulose and how that relates to their relative viability as a biomass feedstock.

s IHblecule? 3. Select the disaccharide(s). Sucrose Fructose Glucose fructose and glucose
9- The hydrolysis of Sucrose (Sucrose+ HO change (AG) of- 6.3 Glucose + Fructose) has a standard free energy kcal/mol; what is the standard free energy change and the equilibrium constant for the synthesis of Sucrose from Glucose and Fructose?
Identify the following reaction: Glucose + Fructose rightarrow Sucrose + Water dehydration synthesis reaction hydrolysis reaction exchange reaction reversible reaction ionic reaction
C. Polysaccharides Drawings Haworth: cellulose using three B-D-glucose monosaccharides Haworth: two a-D-glucose monosaccharides connected with an o-1,6 glycosidic linkage Identify the instructor-prepared model of a polysaccharide as cellulose or amylose. Describe the feature(s) that support your answer. Cellulose
The enzyme sucrase… A. joins sucrose to fructose to form glucose. B. does not affect the energy of activation in the reaction it catalyzes. C. breaks the bond between sucrose and fructose to produce glucose. D. breaks the bond between two glucose monomers. E. generates both glucose and fructose from sucrose.
Sucrose decomposes to fructose and glucose in acid solution. When In (sucrose) is plotted vs. time, a straight line with slope of -0 208 hr results. What is the rate law for the reaction? Rate = 0.208 hr(sucrose) ob Rate = 0.208 hr [sucrose) Woc Rate = 0,0433 hr (sucrose d Rate = 0.0433 hr (sucrose] O Rate = 0.208 mol L-Throucrosojº
A3. The synthesis of sucrose from glucose and fructose is facilitated through the use of ATP as an energy source. The reaction equations for the process, with their Gibbs energy signs, are shown below. glucose + fructose — sucrose ATP + H20 = ADP + Pi AG = Positive AG = Negative glucose + fructose + ATP> sucrose + ADP + Pi Overall AG = Negative Answer A, B, and C. A. The two reactions shown above the line are...
