Concept explainers
Interpretation: Carbohydrates and disaccharides are to be defined. Monomers in carbohydrates; reason for monomers in the table 22.8 to be optically active; monosaccharide units that make up the disaccharide sucrose; bond that forms between monosaccharide units; forces responsible for the solubility of starch in water; difference between starch, cellulose and glycogen is to be stated.
Concept introduction: Initially carbohydrates were believed to be hydrates of carbon.
The carbohydrates are composed of carbon, hydrogen and oxygen and the ratio of hydrogen to oxygen atoms is 2:1. They form a major class of biologically important molecules.
