When researchers build models, they make assumptions about a specific experimental setting and have to choose values for rate constants and other parameters. A theorem, by contrast, can apply to a setting of arbitrary molecular complexity, such as a biochemical network with many components. In a recent study, Shinar and Feinberg (1) formulate a theorem that shows when such biochemical networks exhibit "absolute concentration robustness."
