ABOUT STARCH
Starch is a very common organic matter.
It is a mixture of different organic compounds. On the tops of this argument, I may separe starch in two Main Fractions by standing it in warm water : as a selective solvent, warm water dissolve only a part of starch. By chilling the aqueous system, I may separe an aqueous solution by a flaky matter down standing at the bottom.
AMILOSE and AMILOPECTIN
The water-soluble fraction is named as "Amilose" while "Amilopectin" is few or nor soluble. Despite they are GLUCOSE-POLYMERs bother, I show the more evident difference among the two compounds. On the other hand, I remember you that starch and its extractions undergo coloration by iodine's addiction : Amilose interacts with iodine overcoming to black-blueish hue.
I cannot draw the molecules of Amilose or Amilopectin.
Nonetheless, starting from the AMILOSE's MOLECULAR SKETCH I see that GLUCOSE's UNITs ARE LINKED IN A LINEAR SEQUENCE (e.g. 1- and 4- placements) LEADING TO A Alpha-Helix FASHION TO POLYMER-RAVELING AS A CYLINDRICAL COIL : I said Amilose's molecule is like a Cylindrical Coil or ALPHA-HELIX TYPE.
Nonetheless, starting from the AMILOPECTIN's MOLECULAR SKETCH I see that GLUCOSE's UNITs ARE LINKED IN A NETWORK SEQUENCE (e.g. 1-, 4- and 6- placements) LEADING TO A Crossed FASHION.
ABOUT ENZYMATIC HYDROLYSIS
Starch undergoes hydrolysis forming Cyclo-Dextrines ; Hydrolysis's Terminal Fashion leads to Maltose or the "Alpha-1-O-4-Glucose's Dimer".
Glucose belongs NOT to usual Enzymatic Products.
I hope this helps you.

Ultimately, glucose. Since starch may be of several different kinds including branched and linear forms it is impossible to say with any greater precision.
