Monosaccharides molecular structure molecular structure. . . . . Disaccharides . . 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 alternating residues of and
