1.3 explain the relationship between the structure and function of sucrose

sucrose is a disaccharide made from a condensation reaction between alpha glucose and beta fructose

The condensation reaction involves the formation of water and the bond that forms is a glycosidic bond which is a type of covalent bond.

function of sucrose



sucrose is polar and water soluble but not as reactive as glucose. This makes sucrose a good transport sugar because it is less reactive and so there is faster transport
