Carbohydrates : Carbohydrates Carbohydrates Contain the Elements:
They Are Split Into Three Groups Known As:
Polsaccharides(Polymers) Carbohydrates : 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)n
The n represents the number of times the CH2O unite is repeated. Monosaccharides(monos) : 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. Glucose : 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 : Glycosidic Bond This 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:
Maltose Glycosidic Bond : Glycosidic Bond Above is the structures of a Glycosidic bond.
It forms a Disaccharide Structural formula : Structural formula The structural formula for Maltose.
The structural formula for Lactose. Hydrolysis : Hydrolysis This is the breaking down of a glycosidic bond.
Instead of water been taken away water is added.
Lysis means splitting. Slide 9: By Sarah Kennedy
