Starch has what kind of linkage?

Explanation:
Starch is built from glucose units linked by alpha glycosidic bonds. In the main chain these are alpha-1,4 links, and in amylopectin there are alpha-1,4 bonds with occasional alpha-1,6 branches. This alpha configuration creates a helical, branched polymer that digestive enzymes like amylase readily break down. If the bonds were beta-1,4 (as in cellulose), the molecules would form straight fibers and be much less digestible by humans. So starch uses alpha linkages.
