Question

The difference between amylose and amylopectin is
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

Answer 1

Correct Answer - C
Starch contains two components amylose and amylopectin. Chemically, amylose is a long unbranched chain with 200-1000
`alpha-D-(+)-` glucose units held by `C_(1)-C_(4)` glycosidic linkage.

Amylopectin is a branched chain polymer of `alpha-D-` glucose units in which chain is formed by `C_(1)-C_(4)` glycosidic linkage where branching occurs by `C_(1)-C_(6)` glycosidic linkage.
