Starch is produced by dehydration synthesis. Plants store glucose that is not in use as starch. First, glucose is phosphorylated into glucose-1-phosphate. Starch granules are stored inside the amyloplasts located inside the cells of various plant organs.

How starch is produced?

Most commercial starch is made from corn, although wheat, tapioca, and potato starch are also used. Commercial starch is obtained by crushing or grinding starch-containing tubers or seeds and then mixing the pulp with water; the resulting paste is freed of its remaining impurities and then dried.

How is glucose converted into starch?

The process by which glucose is converted to starch is known as "dehydration synthesis." A water molecule is released as each of the simple sugar molecules of glucose are added to the starch molecule, according to Biology Online.
