Define in brief about the biomolecules

Some of the biomolecules, also known as compounds of life, form part of the structure of cell, and some of these are sources of energy for the cell. A few of them also store energy for the cell and take part in the cellular reactions. The cell is able to synthesise other molecules, needed by the living system, from these compounds. Therefore, the study of the organisation of cells will help us to understand the biological importance of these molecules.
