Quizplus · Accepted Answer

The linkage between the monosaccharide derivatives is a glycosidic bond between the anomeric carbon of F1F1F1S1 and the oxygen atom of F1F1F1S1 in the second monosaccharide. The α and β notation refer to the orientation of the anomeric carbon relative to the ring of the monosaccharide. As the linkage depicted in the options is a β-glycosidic bond, the correct answer is Choice B. Choice A and E both incorrectly include an α-linkage. Choice C and D do not specify the orientation of the anomeric carbon in the first monosaccharide.
