Biology glucose & glycogenWatch
Hi, one of the criteria for OCR AS is 'Explain how the structures of glucose and glycogen molecules relate to their functions in living organisms'. I've already done cellulose and amylose, however I've spent the past hour on the internet and in 3 textbooks looking for information about glucose and glycogen and I can't find anything about how their structures relate to their functions. Can anyone help? Thank you!
It's highly branched structure confers three properties:
It can be broken down into glucose quickly as there are many branch end points that can be targeted at one.
It is compact so you can store more glucose than free glucose.
It is more soluble.

Thus glycogen is a reserve substance of an organism which is saved in muscle and liver cells, while glucose is used as energy when its needed.
