Unknown , November 30, at AM I like it. Unknown , May 13, at PM give reason why it give blue ir brown colour. Unknown , July 10, at PM Thanks. Unknown , August 23, at PM Is the color spectrum significant in this behaviour? Unknown , June 28, at PM I like it so thoughtful. Newer Post Older Post Home. Subscribe to: Post Comments Atom.

Simsek S. The largest use of cellulose is in the manufacture of paper and paper products. Like amylose, cellulose is a linear polymer of glucose. This extreme linearity allows a great deal of hydrogen bonding between OH groups on adjacent chains, causing them to pack closely into fibers part b of Figure As a result, cellulose exhibits little interaction with water or any other solvent. Cotton and wood, for example, are completely insoluble in water and have considerable mechanical strength.
Because cellulose does not have a helical structure, it does not bind to iodine to form a colored product. Cellulose yields D-glucose after complete acid hydrolysis, yet humans are unable to metabolize cellulose as a source of glucose. However, certain microorganisms can digest cellulose because they make the enzyme cellulase, which catalyzes the hydrolysis of cellulose. The presence of these microorganisms in the digestive tracts of herbivorous animals such as cows, horses, and sheep allows these animals to degrade the cellulose from plant material into glucose for energy.
Termites also contain cellulase-secreting microorganisms and thus can subsist on a wood diet. This example once again demonstrates the extreme stereospecificity of biochemical processes. Certified diabetes educators come from a variety of health professions, such as nursing and dietetics, and specialize in the education and treatment of patients with diabetes.
A diabetes educator will work with patients to manage their diabetes. This involves teaching the patient to monitor blood sugar levels, make good food choices, develop and maintain an exercise program, and take medication, if required.
Diabetes educators also work with hospital or nursing home staff to improve the care of diabetic patients. Educators must be willing to spend time attending meetings and reading the current literature to maintain their knowledge of diabetes medications, nutrition, and blood monitoring devices so that they can pass this information to their patients. Starch is the storage form of glucose energy in plants, while cellulose is a structural component of the plant cell wall.
Glycogen is the storage form of glucose energy in animals. What monosaccharide is obtained from the hydrolysis of each carbohydrate? For each carbohydrate listed in Exercise 1, indicate whether it is found in plants or mammals. Describe the similarities and differences between amylose and cellulose. Describe the similarities and differences between amylopectin and glycogen.
Amylose and cellulose are both linear polymers of glucose units, but the glycosidic linkages between the glucose units differ. Help Creative Commons.
