The difference between amylose and amylopectin is

Options

A. amylopectin have 1 `rarr` 4 `alpha`-linkage and 1 `rarr` 6 `alpha`-linkage
B. amylose have 1 `rarr` 4 `alpha`-linkage and 1`rarr` 6 `beta`-linkage
C. amylopectin have 1`rarr`4 `alpha`-linkage and 1 `rarr` 6 `beta`-linkage
D. amylose is made up of glucose and galactose

Answer

A

Explanation

Amylose is a linear polymer of `alpha-D-` glucose linked to one another through glycosidic linkages involving `C_(1)` of one glucose and `C_(4)` of next glucose i.e. `1 - 4 - alpha-` linkage. Amylopectin is a branched chain polymer of `alpha-D-` glucose units in which chain is formed by `C_(1)-C_(4)alpha-` linkages and branching occurs by `C_(1)-C_(6)` `alpha-`glycosidic linkages.
