shows a α-glycosidic bond

shows a β-glycosidic bond, like .

We add a , , and residues.

to observe helical structure

and adition of more glucose residues to reach a molecule

Look from a .

A fragment of amylopectin including .

Zoom in to show a

.

By adding to 25 glucose residues we get a .

to show that branch points are spaced by 24 y 30 glucose residues.

.- Structure like amylopectin but with branch points spaced by 8-12 glucsoe residues.

We add a , a , a and a glucose residue to show the of cellulose molecule (more extended that the amylose one).

and adition of new residues to complete a .

Look from a

A chitin fragment.
