Abstract
Living organisms are composed of a variety of biomolecules such as proteins, nucleic acids, polysaccharides (polymeric forms of sugar molecules), lipids, metabolites, etc. Those biomolecules interact with each other to sustain life in constantly varying environment. For example, signals from environment (such as existence of food) are transferred to inside the cell as a result of interactions of biomolecules (binding of molecules from food that cause delicious smell to receptor proteins in our nose, and consequent conformational changes of the receptor proteins leading to further changes in other signaling molecules) to generate reactions required for the particular situation (secreting enzymes for digestion). One may therefore say that life phenomenon is governed by complex interaction networks of biomolecules.
