  1. Question 1

    Q1. When observing the branched structure of amylopectin in a starch diagram, which specific bond is responsible for the formation of a branch point?

    • A) Alpha 1-4 glycosidic linkages
    • B) Beta 1-4 glycosidic linkages
    • C) Beta 1-6 glycosidic linkages
    • D) Alpha 1-6 glycosidic linkages

    Answer: Alpha 1-6 glycosidic linkages

    Explanation: Alpha 1-6 linkages create branches in amylopectin. Alpha 1-4 is tempting because it forms the linear chain, but doesn't cause branching.
