Answer: starch
Explanation:
starch is a carbohydrate food it is produced by plants and is abundant in seed and tuber.
A cotton shirts requires starch a form of glycocidic bond for its integrity as starch is used on cloth to make it look good.
Starch is made up of amylose and 70%–90% amylopectin. Amylose is a polysaccharide that is made up of D-glucose units joined by the α-1,4-glycosidic linkage with a coiled straight chain. It has six glucose monomers per turn.
Amylopectin is a polysaccharide that has glucose units linked primarily by α-1,4-glycosidic bonds but with occasional α-1,6-glycosidic bonds that causes it branching. One molecule of amylopectin may contain many thousands of glucose units with branches occurring about every 25–30 unit.
