A-E lists experiments performed on an unknown carbohydrate. For A-E, BRIEFLY identify the specific information the experiment provides about the identity and/or structure of the unknown.
A. Complete hydrolysis of the carbohydrate gave glucose and fructose in a 1:1 ratio.
B. Addition of α-glycosidase to the carbohydrate results in formation of glucose and fructose in a 1:1 ratio. Addition of Ã-glycosidase gives the same exact results.
C. Reaction of the carbohydrate with Cu2+ does not result in product formation.
D. CH3I treatment of the carbohydrate followed by complete acid hydrolysis provided 2 products. One of the products is 1, 3, 4, 6, tetra-O-methyl-fructofuranose
E. MS analysis provided a molecular weight of 342.3 g/mol
F. Draw the structure of the carbohydrate below.
