- #49The 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.digAnsr: 1Ans : (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.
