Table of Contents Carbohydrates are classified into two types on the basis of molecular weight. Micromolecules – Monosaccharides and Oligosaccharides (Including Disaccharides) Macromolecules – Polysaccharides The micromolecules have the molecular weight of < 1000 Daltons whereas themacromolecules have > 1000 Daltons as molecular weight. Why do we need carbohydrates in our food? Carbohydrates provides about 50-70% of total energy. We need average carbohydrate requirement in an adult is ~ 400g per day. Essential elements in the constitution of carbohydrate – C. H. O General Formula – *Cx (H2O)y (Containing more than one-OH groups).
