Structure and Functions of Biological Macromolecule

A macromolecule is a molecule which is large in size such as protein. The macromolecules are composed of thousands if covalently bonded atoms. The polymerization of smaller molecules is known as monomers. Many macromolecules are considered as monomers. The most common macromolecules in biochemistry includes biopolymers such as proteins, nucleic acids and carbohydrates and some large non-polymeric molecules such as macrocycles and lipids.
