Biomolecule also called biological molecule, any of numerous substances which are produced by way of cells and living organisms. Biomolecules have a extensive variety of sizes and systems and carry out a massive array of capabilities. The four principal styles of biomolecules are carbohydrates, lipids, nucleic acids, and proteins.Biology and its subfields of biochemistry and molecular biology look at biomolecules and their reactions. most biomolecules are organic compounds, and simply 4 factors—oxygen, carbon, hydrogen, and nitrogen—make up 96% of the human frame's mass. but many other factors, consisting of the diverse biometals, are present in small amounts.The uniformity of each specific styles of molecules (the biomolecules) and of certain metabolic pathways are invariant functions a number of the extensive diversity of life paperwork; for this reason these biomolecules and metabolic pathways are referred to as "biochemical universals" or "idea of material team spirit of the living beings", a unifying concept in biology, together with mobile theory and evolution idea
