Question

Quizplus · Accepted Answer

The formula weight of amylose (C6H10O5)n is less than that of amylopectin (C6H10O5)n+2, because amylose is a linear molecule composed of glucose monomers joined by alpha-1,4 glycosidic bonds, while amylopectin is a branched molecule composed of glucose monomers joined by alpha-1,4 and alpha-1,6 glycosidic bonds. The formula weight of glycogen (C6H10O5)n is greater than that of both amylose and amylopectin, because glycogen is also a branched molecule composed of glucose monomers joined by alpha-1,4 and alpha-1,6 glycosidic bonds, but it is more highly branched and compact than amylopectin. Therefore, the correct order of formula weights is amylose < amylopectin < glycogen, which corresponds to Choice B.
