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

I would like to ask the following since I kinda don't clearly understand the concept behind them: 1. What is Dextrin and how does it differ from glycogen and starch? 2. Would acid hydrolysis (addition of conc. HCl) of starch lead to dextrin or glucose monomers? Kindly show the chemical reaction/s and kindly explain in simple terms. 3. Why is starch a non-reducing sugar? How can you easily differentiate reducing sugars from non-reducing sugar?
