Carbohydrates
Carbohydrate Formation
A condensation reaction is when two molecules join together with the formation of a new chemical bond, and a water molecule is released when the bond is formed
A glycosidic bond forms between the two monosaccharides as a molecule of water is released
A disaccharide is two monosaccharides join together
Glucose + Glucose = Maltose
Glucose + Fructose = Sucrose
Glucose + Galactose = Lactose
Carbohydrate Structure
Is a polymer which is a large, complex molecule composed of long chains of monomers joined together
All carbohydrates contains the elements C,H and O
Monosaccharides
Glucose, fructose and galactose
Glucose is a hexose sugar - a monosaccharide with 6 carbon atoms in each molecule
There are two types of glucose, alpha and beta - they're isomers
Isomer - Molecules with the same molecular formula as each other, but with the atoms connected in different ways
