    The difference between amylose and amylopectin is
    (1) Amylopectin have 1 ``\rightarrow``4 ``\alpha``-linkage and 1 ``\rightarrow`` 6
    ``\alpha``-linkage
    (2) Amylose have 1 ``\rightarrow`` 4 ``\alpha``-linkage and 1 ``\rightarrow`` 6
    ``\alpha``-linkage
    (3) Amylopectin have 1 ``\rightarrow`` 4 ``\alpha``-linkage and 1 ``\rightarrow`` 6
    ``\alpha``-linkage.
    (4) Amylose is made up of glucose and galactose.

    Ans : (1)
    Sol.
    Amylose is long unbranched chain with
    -D-Glucose with held by C1-C4 glucosidic linkage
    whereas amylopectin is branched chain polymer of
    -D glucose unit in which chain is formed by
    C1-C4 glycosidic linkage while branching occurs by
    C1-C6 glucosidic linkage.
