Biological studies

We often say in marketing taglines: Graphs Are Everywhere. When we do so, we are actually describing reality in a very real and fascinating way. Also, in this field, researchers have known for quite some time that biological components (proteins, molecules, genes, and so on) and their interactions can accurately be modelled and described by means of a graph structure, and doing so yields many practical advantages. In metabolic pathways (see the following diagram for the human metabolic system), for example, graphs can help us understand how the different parts of the human body interact with each other. In metaproteomics (the study of all protein samples taken from the natural environment), researchers analyze how different kinds of proteins interact with one another and are used in order to better steer chemical and biological production processes.
