                                Water is a chemical compound with the formula H2O, and despite being essential for all life, it is not a macromolecule. Composed of only three atoms, it is a simple molecule with unique properties that allow it to play a crucial role in biological systems. This article explores why water is not a macromolecule and how it differs from these larger, more complex structures.
