Maltose OOO So what’s our relationship? Its called α-1—4 glycosidic bond

Maltotriose OO O O O So what’s our relationship? Of course! It’s the α-1—4 glycosidic linkages

Iso- maltose OO O So what’s our relationship? Its called α-1—6 glycosidic bond

Trehalose OOO So what’s our relationship? Its called α-1—1 glycosidic bond, is’nt it cool?

Lactulose O O O O O O So what’s our relationship? Its called β-1—2 glycosidic bond I don’t understand!

OO O O OOO Amylose We’ve got a strong relashionship, the α-1—4 glycosidic linkage

OO O O OOO Amylo-pectin O O O O We are stronger, we have got α-1—4 glycosidic linkages as well α-1—6 branch points
