A level Biology HELP!!Watch
Also why is it important that the two isomers of glucose exist?
It is a disaccaride as it is two different monomers joining together to make 1 'thing' for lack of a better word. If you are asking why its not a polysaccaride it is because it is not a repeating unit but just two joined together by a glycosidic bond. I am not sure how much of that makes sense to you but it is the only way it makes sense in my head
Sorry I don't know the answer to the first part but the second part I assume is because they make different structures .
Eg alpha glucose joined to get her to make polysaccharides like starch and glycogen which are very good for energy storage but beta glucose joins together to make cellulose which has a durable rigid structure making it adapted to its function of making cell walls (cell walls keep plant cells in their shape)
