Plant polysaccharides are invaluable not only for plant life but also for their significant impact on nutrition and industry, making them a crucial area of study in both science and technology. Plant polysaccharides are complex carbohydrates that consist of long chains of monosaccharide units linked by glycosidic bonds. They are integral to the structure and function of plants, serving various roles in plant biology and human nutrition. Plant polysaccharides are essential in human diets, particularly as dietary fibers. They promote digestive health, regulate blood sugar levels, and contribute to overall well-being. Common sources include fruits, vegetables, grains, and legumes. Due to their unique properties, plant polysaccharides are widely used in various industries, including food, pharmaceuticals, and biodegradable materials. They serve as thickeners, stabilizers, and gelling agents, enhancing the texture and shelf life of food products. Their diverse functions and applications make them a valuable topic of study in fields ranging from nutrition to materials science.
