BACKGROUND Although water is regarded as a simple molecule, its ability to create hydrogen bonds makes it a highly complex molecule that is crucial to molecular biology. Water molecules are extremely small and are made up of two different types of atoms, each of which plays a particular role in biological processes. Despite substantial research, understanding the hydration chemistry of protein-ligand complexes remains difficult. Researchers are working on harnessing water molecules to solve unsolved challenges as a result of the development of computer technologies. OBJECTIVE The goal of this review is to highlight the relevance of water molecules in protein environments, as well as to demonstrate how the lack of well-resolved crystal structures of proteins functions as a bottleneck in developing molecules that target critical therapeutic targets. In addition, the purpose of this article is to give a common platform for researchers to consider numerous aspects connected to water molecules. CONCLUSION Considering structure-based drug design, this review will make readers aware of the different aspects related to water molecules. It will provide an amalgamation of information related to the protein environment, linking the thermodynamic fingerprints of water with key therapeutic targets. The review has mentioned about a large number of computational tools available to study the water network chemistry with the surrounding protein enviornment. It also emphasises the need for computational methods in addressing gaps left by a poorly resolved crystallized protein structure.
