⒈ organic compounds. It is mostly found in the grains of cereal plants, the roots of sweet potatoes and the tubers of potatoes. It is the main carbohydrate food. Industrially used to make alcohol, sugar, etc.
2. Mandarin Dictionary
A polysaccharide. Found in large amounts in the roots, stems, and seeds of plants. It cannot be directly absorbed and utilized by the human body. It must first be hydrolyzed into soluble starch, dextrin, maltose, and finally glucose before it can be absorbed by the human body.
3. Network explanation
Starch Starch is a polymerization of glucose molecules. It is the most common storage form of carbohydrates in cells. Starch is also called starch in the catering industry. Its general formula is (C6H10O5)n. When hydrolyzed to the disaccharide stage, it becomes maltose. The chemical formula is C12H22O11. After complete hydrolysis, it obtains monosaccharide (glucose). The chemical formula is C6H12O6. There are two types of starch: amylose and amylopectin. The former is an unbranched helical structure; the latter is composed of 24 to 30 glucose residues connected end-to-end by α-1,4-glycosidic bonds, with α-1,6-glycosidic bonds at the branches. Amylose turns blue when exposed to iodine, and amylopectin turns purple when exposed to iodine. This is not due to a chemical reaction or interaction between starch and iodine, but because the hole in the center of the starch helix can accommodate iodine molecules, and through van der Waals forces, the two form a blue-black complex. Experiments have shown that iodine molecules alone cannot turn starch blue. In fact, it is the iodine molecular ion (I3) that turns starch blue. Starch is a nutrient stored in plants. It is stored in seeds and tubers. The starch content in all types of plants is high. Starch can be thought of as a high polymer of glucose. In addition to being edible, starch is also used industrially to make dextrin, maltose, glucose, alcohol, etc. It is also used to prepare printing paste, sizing textiles, gluing paper, and pressing pharmaceutical tablets. It can be extracted from starchy substances such as corn, sweet potato, wild acorns and kudzu root.
