Question

What is a difference between starch and glycogen?

Answer 1

There are two forms of starch, amylose and amylopectin. Amylose is a straight chain polymer of glucose with all of the units linked by alpha (1-->4) glycosidic bonds. Amylopectin has a similar structure except that it has alpha (1-->6) branch points every 24 to 30 glucose residues.

Glycogen is very similar to amylopectin except that glycogen has more extensive branching. It has alpha (1-->6) branch points every 8 to 14 glucose residues.
