This research examines how natural sugar-based compounds (polysaccharides) from plants, fungi, and other sources can act as powerful antioxidants for medical treatments and applications. These natural compounds help protect cells from damage caused by harmful molecules called free radicals, which are linked to many chronic diseases. Impacts on everyday life: – Natural polysaccharides could lead to safer and more effective medications with fewer side effects – These compounds can be used to create better food packaging that keeps food fresh longer – They can help create improved wound healing materials and tissue repair treatments – Natural polysaccharides offer environmentally friendly alternatives to synthetic materials in medical and food applications – These compounds could help develop better treatments for common conditions like diabetes and heart disease
