give one example of charbohydrate being used as information molecule, explain

Although the first two carbons of fructose and glucose are identical in structure to DHAP and GADP (from glycolysis), DHAP and GADP equilibriate on their in solution to favor the ketone over the aldehyde, while fructose and glucose do not.  Why? a)The larger size of the molecule sterically hinders the isomerization b)The larger sugars have more OH groups which hydrogen bond and disrupt isomerization c)The larger sugars cyclize, and there is no carbonyl to isomerize in the cyclic form d)The larger sugars cyclize, and in the cyclic form the hydrogen bonding is very strong e)The larger sugars are less soluble in water than the smaller sugars

Draw a lipid exhibiting both an ether-linked and ester-linked acyl group attached to a glycerol phosphate backbone. Then attached an appropriate head group to the phosphate (ethanolamine, choline, serine, etc.)

There are some similarities and differences in the structure and function of starch and cellulose. Briefly compare these two substances and describe two major differences and two similarities of these substances.
