Which glycan contains a covalently linked dimeric protein that functions as a protein anchor?
A) amylose
B) glycogen
C) amylopectin
D) cellulose

Question

Quizplus · Accepted Answer

Glycogen contains a covalently linked dimeric protein called glycogenin, which functions as a protein anchor. Glycogenin catalyzes the formation of a glycogen molecule by adding glucose residues to itself, and then serves as the primer for further glycogen synthesis. Amylose, amylopectin, and cellulose are all polysaccharides composed of glucose residues but do not contain protein anchors.
