Biochemsitry:
Deduce the structure of the disaccharide trehalose from the information given below. Draw trehalose and the products of hydrolysis.
a) complete hydrolysis yields only D-glucose
b) it is hydrolyzed to monomers by a-glucosidase but not by b-glucosidase
c) it does not reduce cu2+ to cu+

Distinguish the two methodologies used for getting a complete protein structure. Will the structural image from either method be the exact structure of the protein in vivo? Explain why or why not.
Mechanistic probes often require the use of an electrophilic functional group to interact with an especially-reactive amino acid in the protein active site. For each of the follow functional groups that can be used in a mechanistic probe, provide a structure of the product.
