shows a α-glycosidic bond

shows a β-glycosidic bond, like .

Polysaccharides

  • Starch
    • Amylose
We add a , , and residues.
to observe helical structure
and adition of more glucose residues to reach a molecule
Look from a .
    • Amylopectin.-
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.
  • Cellulose.-
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 polymer of .
A chitin fragment.
  • .- Heteropolysaccharide with and
