Chemical Perturbations

Definition

Chemical perturbations refer to alterations in the normal biochemical environment of a biological system caused by the introduction of external chemical agents. These perturbations can affect cellular processes, signaling pathways, and overall system behavior, helping to assess how resilient or robust biological networks are when faced with disruptions. Understanding these effects is crucial for quantifying how networks respond to changes and for predicting the potential impacts on biological functions.
