Which of the following category of biomolecules does Starch belong to?

Starch is a complex carbohydrate that serves as the primary energy storage molecule in plants [2]. It is classified as a polysaccharide, which is a large macromolecule composed of long chains of glucose units linked together by glycosidic bonds [5]. During photosynthesis, plants produce glucose, a simple carbohydrate, which is subsequently converted into starch for long-term storage in various organs like tubers and seeds [4]. In the human diet, starch is found in staples such as rice, potatoes, and wheat [5]. Upon consumption, digestive enzymes in the saliva and small intestine break down these complex starchy chains back into simple glucose units to provide energy for the body [5]. Unlike proteins, lipids, or nucleic acids, starch is specifically an alpha-glucan carbohydrate consisting of two types of molecules: linear amylose and branched amylopectin [5].
