Biomolecule

A biomolecule or biological molecule is a loosely used term for molecules and ions  present in organisms that are essential to one or more typically biological processes, such as cell division, morphogenesis, or development.Biomolecules include large macromolecules  such as proteins, carbohydrates, lipids, and nucleic acids, as well as small molecules such as primary metabolites, secondary metabolites, and natural products. A more general name for this class of material is biological materials. Biomolecules are usually endogenous, produced within the organisms. Most biomolecules are organic compounds, and just four elements—oxygen, carbon, hydrogen, and nitrogen—make up 96% of the human body's mass. But many other elements, such as the various biometals, are present in small amounts.
