Answer 1

25. (B) Monosaccharides all centain bike Carbons, The above statement is the not the feature of Monosaccharides as monarccharides can be triose (3 carbon) tetrose (u Carben) pentose (5 Carben) hехол. (« Carlom) . 26) Disaccharides are the molecules like hactose, Maltose or sucuse which upon hydrolysis gives two simplest carbohydrate units (Monosaccharides). Oligosaccharides are the molecules which upon hydrolysis. gives 2 to lo monosaccharide wailo . Polysaccharides are the molecules which upon hydrolysis gines very many monosaccharice units (simplest Carbohydrate units), for eg starch Cellulose etc. Answer is (E)
