Carbon is a key element found in all carbohydrate, lipids, proteins and nucleic acids, which are all organic macromolecules.
The fundamental component of all these macromolecules is carbon. The carbon atom has the unique ability to form covalent bonds with as many as four different atoms, making it the best or ideal element to form the backbone or basic structural component of the macromolecules.
Carbon easily bonds with non - metallic elements and due to this, it is termed often as the building block of life.
