title: Amino acid titration curves--misshapen or mislabeled?
abstract: Titration curves are frequently used to illustrate the change in charge of amino acids with pH, and as such are a fundamental part of most biochemistry courses. We have noticed that the graphs of titration curves appearing in many biochemistry textbooks are drawn incorrectly near the origin of the titration. This article demonstrates that this curve is misshapen, or, alternatively, that the axis of the graph is incorrectly labelled.
