AQA A Level Biology Carbohydrates
Monosaccharides - The monomer from which larger carbohydrates are made.
Disaccharides - Formed by the condensation of 2 monosaccharides.
Polysaccharides - Formed by the condensation of many monosaccharides.
Glucose - C6H12O6
Structure of glucose
Soluble (OH groups form H bonds with water).
Easily transported. The bonds contain a lot of energy; used in respiration to make ATP.
What is an isomer?
Same molecular formula but differently arranged atoms.
Disaccharides and how they are formed
Glucose + Glucose = Maltose
Glucose + Fructose = Sucrose
Glucose + Galactose = Lactose
How are glycosidic bonds formed?
A condensation reaction between two monosaccharides forms a glycosidic bond.
The removal of a water molecule.
