This document presents a methodology for vertically translating between molecular and organismal levels in biological feedback loops. It discusses modeling techniques like Michaelis-Menten kinetics and non-competitive inhibition that can be used as "building blocks" for models. Computer simulations demonstrate how molecular interactions modeled with these techniques can translate to global behavior at the organismal level. The goal is to develop a standardized approach to link molecular mechanisms to physiological processes through mathematical modeling of feedback loops.

4. The coordinated physiological processes which
maintain most of the steady states in the
organism are so complex and so peculiar to
living beings – involving, as they may, the
brain and nerves, the heart, lungs, kidneys and
spleen, all working cooperatively – that I have
suggested a special designation for these
states, homeostasis.
Walter B. Cannon 1932

So, we coined a new word, allostasis, to
emphasize two key points about
regulation: parameters vary, and
variation anticipates demand.
