How is amylose formed

Joining together a large number of alpha glucose molecules makes the polysaccharide amylose

The alpha glucose molecules are joined by 1,4 glycosidic bonds, each bond forms in a condensation reaction producing a molecule of water.

Amylose twists into complex helix with hydrogen bonds forming between glucose molecules along the chain
