Is banana a starch?
During fruit development, bananas accumulate large amounts of starch (between 15 and 35% w/w of their fresh weight, depending on the cultivar). Pulp softening and sweetening during banana ripening are attributed not only to changes in the activities of cell wall hydrolases but also to starch-to-sugar metabolism.
What is a starch molecule?
Starch is a chain of glucose molecules which are bound together, to form a bigger molecule, which is called a polysaccharide. There are two types of polysaccharide in starch: Amylose – a linear chain of glucose. Amylopectin – a highly branched chain of glucose.
