All living beings and non-living objects around us are composed of molecules in precise and systematic manner. For example, water is made up of molecules of water and a molecule of water contains hydrogen and oxygen atoms.
Similarly, living organisms are made up of various types of molecules known as bimolecular. These are large molecules known as macromolecules.
The macromolecules are made up of smaller molecules called building blocks or units. The major bimolecular found in living organisms are (1) carbohydrates, (2) proteins, (3) lipids and (4) nucleic acids. If we consider a carbohydrate as an exemplary bimolecular, it is found to be made up of basic units (monomers) called monosaccharide’s. Starch and cellulose are carbohydrates present in plants.
These are made up of monosaccharide units called glucose. Several glucose units join with each other and give rise to polymers known as starch and cellulose. All bimolecular usually contain carbon (C), hydrogen (HE) and oxygen (O) atoms. Since, all bimolecular contain carbon atoms; they are also known as bio-organic molecules. Summarizes the nature of bimolecular.
