Diagram showing orientation and location of different alpha-glucan linkages.

α-Glucans (alpha-glucans) are polysaccharides of D-glucose monomers linked with glycosidic bonds of the alpha form.

Examples of alpha glucans

dextran, α-1,6-glucan
glycogen, α-1,4- and α-1,6-glucan
pullulan, α-1,4- and α-1,6-glucan
starch, α-1,4- (such as amylose) and α-1,6-glucan (including amylopectin)^[1]

Examples of alpha-glucan molecules with different glycosidic bonds.
