Biomolecules: NEET questions with solutions
NEET tests the evidence for glucose structure, anomers and glycosidic links in sucrose, maltose and lactose, reducing versus non-reducing sugars, levels of protein structure, denaturation, vitamins and their deficiency diseases, and DNA versus RNA. Marks are lost on which sugars are reducing and on which vitamins are water-soluble.
