Molecules of life: biological molecules all biological systems are based on the same biological molecules the details of those molecules differ among organisms. Living systems are composed of organic chemicals the complex organic molecules which form the basis of life ie which build up living organisms and are required for their growth and maintenance are called bio molecules. Organic molecules always have covalent bonds, and are also called molecules of life because all living things are mostly composed of them organic molecules receive that name because they always have a backbone of carbon (c), and other atoms as oxygen (o), hydrogen (h), nitrogen (n), and phosphorus (p. Many carbohydrates have empirical formuli which would imply about equal numbers of carbon and water molecules for example, the glucose formula c 6 h 12 o 6 suggests six carbon atoms and six water molecules.
