Some common examples of carbohydrates are cane sugar, glucose, starch, etc.Most of them havegeneral formula {Cx(H2O)y}CarbohydratesCarbon + WaterHydrates of carbonCarbohydratesGlucoseC6H12O6C6(H2O)6Fits into the general formula Cx(H2O)yWhere, x = y = 6ExampleCarbohydratesDoes all the compounds that t into Cx(H2O)ycan be considered as carbohydrates? Answer: No !!Acetic acidCH3COOHC2(H2O)2Fits into the general formula Cx(H2O)yNot a carbohydrateExamplesRhamnoseC6H12O5Does not t into Cx(H2O)yA carbohydrateCarbohydratesMost of them havegeneral formula {Cx(H2O)y}CarbohydratesCarbon + WaterHydrates of carbonCarbohydratesModern denition of carbohydratesOld denition of carbohydratesPolyhydroxy aldehydes or ketonesMultiple -OH groupsGlucose, fructose etc.ExamplesClassication of CarbohydratesGenerally, carbohydrates are optically active.Substances that rotate the plane of polarized lightTasteBehaviour on hydrolysisReducing natureClassication onthe basis ofClassication of CarbohydratesSugars Non-sugarsOn the basis of taste, carbohydrates can beSugars1.Milk sugar (lactose)2.Cane sugar (sucrose)Carbohydrates that are sweet in taste are called sugars.Also known as saccharides.ExamplesClassication of CarbohydratesSaccharides in GreekSakcharon means sugarMilk sugar (lactose)Cane sugar (sucrose)Classication of
