Detailed explanation-1: -Polysaccharides are polymers consisting of chains of monosaccharide or disaccharide units joined by glycosidic bonds with different number of C (e.g. six for a hexose such as glucose).
Detailed explanation-2: -Polysaccharides are polymeric carbohydrates composed of long chains of monosaccharide units joined by glycosidic linkages with a general formula of (C6H10O5)n, 40≤n≤3000.
Detailed explanation-3: -A polysaccharide is a large molecule made of many smaller monosaccharides. Monosaccharides are simple sugars, like glucose. Special enzymes bind these small monomers together creating large sugar polymers, or polysaccharides.
Detailed explanation-4: -Monosaccharides are the simplest form of carbohydrates and are composed of a single molecule or subunit. The disaccharides are composed of two monosaccharides linked together, and polysaccharides are composed of 3 or more monosaccharides linked together.
