Because they contain less "built-in" water.

Explanation:

When two glucose molecules 'decide' to bond, they lose a molecule of water:

#2C_6H_12O_6->C_12H_22O_11+H_2O#

And this happens at every connection between glucose molecules, so in a long chain a lot of water is lost. The water does not contribute anything to the energy content of the compound.
