Amylose is the name given to linear sections of the starch molecule consisting of α (alpha) 1,4 linked glucose units.

This model shows 40 glucose units, forming a single helical structure, with about 7 glucose units per turn, as can be seen when looking into the end of the molecular tube.This structure is stabilised by Hydrogen bonds, between -oH of C3 and -Oh of C2 in the next glucose unit.

Incidentally, iodine migrates into the space within the molecule and gives the characteristic blue-black colour used in the starch test.
