Amylose structure

The α(1→4) bonds promote the formation of a helix structure. The structural formula of amylose is pictured at right. The number of repeated glucose subunits (n) can be many thousands.


Amylose starch is less readily digested than amylopectin, however takes up less space so is preffered for storage in plants; it is how about 80% of the starch in plants is stored. The digestive enzyme amylase works on the ends of the starch molecule, breaking it down into sugars.
