I'm supposed to draw Hayworth's formula for disaccharide of
a) cellulose---- cellobiose
c0 amylopectine-----maltose and isomaltose
d) glycogen -----???????
I'm having trouble finding a disaccharide for glycogen. Any help ???

The way I recommend students to remember which isotope of glucose (coming to disaccharides in a sec) is present in various polysaccharides, is to remember the polysaccarides in the following order:
Mnemonic: Amy and Andy are Good Chums!
and the corresponding glucose isotopes being: alpha, beta, alpha, beta in that order. i.e. amylose: alpha; amylopectin: beta, glycogen: alpha; cellulose: beta. (the human hippocampus has a predilection to more readily permit storage and subsequent retrieval of info in certain specific formats, one of them being symmetry/order/sequence - you will be very aware of how you start thinking of the next song/tune in your collection as soon as the previous one is about to end, when you have listened to that album a few times - same principle).
So, if glycogen contains alpha glucose, and you know that glycogen is highly branched (has both 1, 4 and 1, 6 linkages), you can work out the disaccharides that comprise the intermediaries in the process of glycogenolysis (breakdown of glycogen into alpha glucose)
Hope this helps!
