Sample Question 1
What is a glycosidic bond, and how is it formed between two monosaccharide units?

A covalent bond formed between the anomeric hydroxyl of one monosaccharide and a hydroxyl group of another through a dehydration reaction that releases one water molecule

A non-covalent hydrogen bond formed between hydroxyl groups of adjacent sugar molecules that can be reversibly broken without loss of water

A covalent bond formed when the hydroxyl of one sugar reacts with a phosphate group on another sugar, releasing inorganic phosphate

A peptide bond formed between the amine group of one sugar and the carboxyl group of an adjacent sugar unit during polymerization

Sample Question 2
What is the key structural difference between the alpha-1,4-glycosidic bonds in starch and the beta-1,4-glycosidic bonds in cellulose?

Both starch and cellulose use identical glycosidic bonds but the glucose monomers exist in different sequences of chemically modified sugar variants

Starch glycosidic bonds involve covalent phosphate bridges while cellulose bonds involve direct carbon-to-carbon linkages without an oxygen bridge between residues

In starch the bond forms between carbon one and carbon six while in cellulose it forms between carbon one and carbon three of adjacent glucose units

In starch the anomeric carbon is in the alpha configuration when the bond forms, while in cellulose each glucose is in the beta configuration and rotated 180 degrees relative to its neighbor

Sample Question 3
Amylose and amylopectin are both components of starch but differ in that amylopectin contains alpha-1,6-glycosidic branch points while amylose does not.
