Question
**Question 27:** Which correctly describes the furanose form of a monosaccharide? a) Six-sided ring structure with five carbon atoms and one oxygen atom b) Boat conformation of a monosaccharide, not the chair conformation c) Linear structure of a monosaccharide, not the cyclic structure d) Five-sided cyclic structure with four carbon atoms and one oxygen atom e) Chemical derivatives of monosaccharides, such as amino sugars with an amino group attached **Question 28:** In aqueous solution, monosaccharides such as glucose can exist as cyclic or linear structures. The percentage of monosaccharides that are in the cyclic form is: a) More than 99% b) 50% c) 10% d) 5% e) Much less than 1% **Diagram:** The diagram shows a hexagonal ring with various atoms attached. It has an oxygen atom incorporated in the ring and various hydroxyl (OH) groups and hydrogen atoms attached. The monosaccharide structure shown here is: a) α-fructose b) β-ribose c) β-fructose d) α-galactose e) β-glucose **Question on Cellobiose:** Which of the molecules below is cellobiose, a breakdown product of cellulose? a) glucose-α-1,4-glucose b) glucose-α-1,2-fructose c) glucose-β-1,4-glucose d) galactose-β-1,4-glucose e) glucose-α-1,6-glucose
