I did the January 2012 exam as a mock a couple of weeks back and barely scraped an A. I'm hoping the grade boundaries for the May one will be similar though, it would be very beneficial!
can someone please explain the difference between glycogen, amylose and amylopectin.
also do we need to know about microfibrils and macrofibrils when describing the structure and function of cellulose.
thanks
glycogen is the energy storage molecule in animals. It is made up of alpha glucose subunits bonded together by 1,4 glcosidic bonds. There are many branches which makes it compact and easy to break of bits and generate/release energy. it is very compact so good for storage.
Amylose and amylopectin are storage molecules in plants. Amylose is a straight chain and coils to make it compact and good for storage while amylopectin is branched so can be broken down easily so glucose(energy) can be released

hope this helps
thanks for your help
so animals dont have amylose and amylopectin. and how does this link with starch???
