Starch is easily hydrolyzed, as in human mouth ans small intestine .
No, it is negative
It speeds up the reaction so amylase works faster.
hydrolyse substances
The presence of starch can be detected by adding 2 drops of the iodine solution. If starch is present a black/dark blue color is formed. If there is a yellow color (caused by the iodine) no starch is present.

Amylase is an enzyme that breaks starch down into sugar. Amylase is present in human saliva, where it begins the chemical process of digestion. Foods that contain much starch but little sugar, such as rice and potato, taste slightly sweet as they are chewed because amylase turns some of their starch into sugar in the mouth. Thepancreas also makes amylase (alpha amylase) to hydrolyse dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. Plants and some bacteria also produce amylase. As diastase, amylase was the first enzyme to be discovered and isolated (by Anselme Payen in 1833).[1]

In plants, glucose is generally stored as starch.
Corn starch is a souluble starch.
