    The difference between amylose and amylopectin is                [NEET - 2018]

    A)  Amylopectin have 1\[\to \]4 \[\alpha \]-linkage and 1\[\to \]6 \[\beta \]-linkage

    B)  Amylose have 1\[\to \]4 \[\alpha \]-linkage and 1\[\to \]6 \[\beta \]-linkage

    C)  Amylopectin have 1\[\to \]4 \[\alpha \]-linkage and 1\[\to \]6\[\alpha \]-linkage

    D)  Amylose is made up of glucose and galactose

    Correct Answer: C

    Solution :

    Amylose and Amylopectin are polymers of \[\alpha -\]D-glucose, so \[\beta \]-link is not possible. Amylose is linear with 1\[\to \]4 \[\alpha \]-linkage whereas Amylopectin is branched and has both 1\[\to \]4 and 1\[\to \]6 \[\alpha \]-linkages. So option [c] should be the correct option.
