and


Yes but like in maltose;
HO-[Cchain]-O-[cchain]-OH is it the same thing ? when drawing starch or should I just leave the ends open ?
Leave the ends open for all the polymers because they are unsaturated. More and more atoms can be added to them.

guys how to find the excess in sticom??
From the mass of the reactants given, and the mole ratio, find how much of the other substance is needed to react completely with the amount of the first substance given. If the mass of the second substance is more than needed, it is in excess. Otherwise, the first substance is in excess.
