Molecular forms and functions by- Chloe What are Atoms? A molecule is the smallest particle in a chemical or compound that has the chemical properties of that element or compound. Molecules ar e made up of atoms t hat are held together by chemical bonds. These bonds form as a result of the sharing or exchange of electrons among atoms. The atoms of certain elements readily bond with other atoms to form molecules. What are M acro-molecules ? A molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer.There are four major classes of biological macro-molecules. For example, carbohydrates, lipid, proteins, nucleic acids. Each of these types of macro-molecules performs a wide array of important functions wi thin the cell. In combination, these biological macro-molecules make up the majority of a cell’s dry mass. All the molecules both inside and outside of cells are situated in a water-based environment, and all
