When starch is hydrolyzed, monomer glucose is produced.

[(c6h10o5) n]+nh2o → nc6h12o6 (write enzyme above arrow)

The standard reaction equation is shown in the figure:

Starch reacts with water to produce starch hydrolysis. The chemical equation of starch hydrolysis is (c6h10o5) n+nh2o-H2SO4 → nc6h10o6. When dextrin, the intermediate product of starch hydrolysis, reacts with iodine, the color changes from purple brown to yellow. If starch is not completely hydrolyzed, different colors will appear.

Starch is a high molecular compound, which can be hydrolyzed under certain conditions. Dilute sulfuric acid can be added and heated. Starch is not only an important polysaccharide, but also a natural polymer compound with relatively large molecular weight.

Although it is sugar, it has no sweetness. It is white powder and insoluble in cold water. In hot water, starch granules will expand, some starch will be dissolved in water, and the other part will be suspended in water, forming a gelatinous starch paste.

After starch enters the human body, a part of starch is hydrolyzed by amylase contained in saliva to produce maltose; Under the action of amylase secreted by small intestine and pancreas, the remaining starch is hydrolyzed to maltose.

Under the catalysis of maltase in intestinal juice, maltose is hydrolyzed into glucose which can be absorbed by human body and used for the nutritional needs of human tissues. Equation: (c6h10o5) n+(n-1) H2O → nc6h12o6.
