Abstract
The proper functioning of enzymes in bodily fluids requires that the pH be maintained within rather narrow limits. The first line of defense against large pH fluctuations in such fluids is the passive control provided by the presence of pH buffers. It is equally important for many enzymes that the redox potential is kept within a narrow range. In that case, stability of the potential is most readily achieved with a redox buffer. In this communication the redox buffer strength is defined by analogy with acid-base buffer strength.

Unified Approximations: A New Approach for Monoprotic Weak Acid-Base Equilibria
Harry L. Pardue , Ihab N. Odeh and Teweldemedhin M. TesfaiJournal of Chemical Education2004 81 (9), 1367Unified Approximations: A New Approach for Monoprotic Weak Acid-Base Equilibria
Harry L. Pardue , Ihab N. Odeh and Teweldemedhin M. TesfaiJournal of Chemical Education2004 81 (9), 1367This article describes a new approach to approximate calculations for monoprotic acid–base equilibria in otherwise pure water. The new approach, identified herein as unified approximations, uses a simple decision criterion to select between situations ...
