Lactose is a disaccharide sugar composed of two monosaccharides, glucose and galactose, linked together by a β-1,4-glycosidic bond. This means that the glucose and galactose molecules are joined together by a specific type of chemical bond.

Esters are structured with a carbon atom double-bonded to one oxygen atom and single-bonded to another oxygen atom, which is also bonded to an alkyl or aryl group.
