Macromolecules have a major role in everyday life, we might not notice this because we don't exactly know what we use them for and why they are so important to us, mainly because we can see them therefore we are not aware that they exist.

The term macromolecules is sometimes used to refer to aggregates of two or more macromolecules held together by intermolecular forces rather then by chemical bonds. Another common macromolecule property that does not characterize smaller molecules is the need for assistance in dissolving into solution. Many require salts or particular ions to dissolve in water. Cells can combine small molecules into large macromolecules, forming a higher level in the biological hierarchy. Macromolecules are polymers, chains of identical or similar subunit molecules called monomers. Although there is a limited number of monomers common to all organisms, each organism is...
