1 Carbohydrates Contain the Elements: CarbonHydrogenOxygenThey Are Split Into Three Groups Known As:Monosaccharides(Monomers)Disaccharides(Dimers)Polsaccharides(Polymers)
2 Carbohydrates Many carbohydrates are soluble in water. The usual chemical test for the simpler carbohydrates is heating with Benedicts solution.The formula for a carbohydrate is (CH2O)nThe n represents the number of times the CH2O unite is repeated.
3 Monosaccharides (monos) The Most Important Monosaccharide Is Glucose.A Monosaccharide is made up of 1 sugar unit.Monos are reducing sugars.Fructose and Galactose are all so Monosaccharides, They all have the same chemical formula but different structures.
4 Glucose The chemical formula for glucose is C6H12O6. It is a six sided ring.The structure on the left is a simplified structure of glucose
5 Glycosidic BondThis is when two monosaccharides join to form a Disaccharide.The reaction is similar to condensation.The reaction involves the water been given off.There are three types of Disaccharides:SucroseLactoseMaltose
6 Glycosidic Bond Above is the structures of a Glycosidic bond. It forms a Disaccharide
7 Structural formula The structural formula for Maltose. The structural formula for Lactose.
8 Hydrolysis This is the breaking down of a glycosidic bond. Instead of water been taken away water is added.Lysis means splitting.
