In a recent study, researchers investigated the structural differences and functional implications of various polysaccharides. One focus was on the variation in glycosidic linkages found in these carbohydrate polymers. The researchers discovered that certain polysaccharides derived from plants have beta-glycosidic bonds, while others exhibit alpha-glycosidic bonds. They noted that cellulose, a major component of plant cell walls, contains beta-1,4-glycosidic bonds, which contribute to its rigidity and insolubility in water. In contrast, starch, which serves as an energy reserve in plants, is composed of alpha-1,4-glycosidic bonds, allowing it to be more readily digestible.
Based on this information, which of the following statements is true regarding the digestibility and water solubility of these carbohydrates?
