Give a brief account of solution structures of 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.

Is Cellulose ketohexose or aldohexose? How does Cellulose give result in Seliwanoff’s test (any color change)?
True /False Cellulose is the skeleton of most plant structures. Eustress is unique to people in Europe. Who is the acronym of World Health Order. Carbs are carbohydrates and involve sodium at the molecular level. Calorie dense refers to someone who doesn’t understand calories.
As clearly indicated by the three-dimensional structures, the _____ glycosidic linkage of cellulose results in a linear structure in which each successive glucose monosaccharide is ______. β1,4; rotated about its C4-O1 bond by 180˚ ˚ α1,4; rotated about its glycosidic bond by 180˚ α1,4; rotated about its C4-O1 bond by 180˚
Question 10 2 pts If you fill up a cellulose bag with a solution of sucrose and table salt; then immerse the cellulose bag into a beaker filled with iodine diluted in water. After 1 hour, you observe the following: the solution in the beaker has become black; the solution inside the cellulose bag is also black. What is your conclusion? lodine turned black because of the presence of proteins Starch leaked out of the bag and iodine diffused into...
Please give a brief explanation as to why the following answers are correct. a. Which solution should be the strongest electrolyte: 0.20 M BaCl2, 0.25 M NaCl, or 0.50 M sucrose? Answer: 0.20 M BaCl2 > 0.25 M NaCl > 0.50 M sucrose. Give an explanation as to why this answer is correct involving the number and kinds of particles present in solution. Explanation: B. Arrange the substances water (H2O), propane (C3H8), and ethanol (CH3CH2OH) in terms of their predicted...
Give a brief description of each: Trees and forests Vector spaces associated with a graph Representation of graphs by binary matrices and list structures Traversability Connectivity Planar graphs Colorability Directed graphs
An agronomist examines the cellulose content of a variety of alfalfa hay. Suppose that the cellulose content in the population has standard deviation ? = 9 milligrams per gram (mg/g). A sample of 15 cuttings has mean cellulose content x = 145 mg/g. (a) Give a 90% confidence interval for the mean cellulose content in the population. (Round your answers to two decimal places.) , (b) A previous study claimed that the mean cellulose content was ? = 140 mg/g,...
