WebStarch: structure. Starch is the storage polysaccharide of plants; It is stored as granules in plastids (e.g. chloroplasts) and amyloplasts (small, membrane-bound organelles containing starch granules) Due to starch molecules being large polymers consisting of thousands of glucose monomers, starch takes longer to digest than glucose WebStarch is a polysaccharide formed by units of glucose and the storage form of carbohydrates in plants. It is synthesized by the most part of vegetable cells and stored especially in seeds (e.g. cereals and legumes), tubers (e.g. potatoes), roots (e.g. those of carrots) and some fruits (e.g. green banana).
