Abstract
IT has been shown by Wolstenholme and Schulman1,2 that metal ions such as Fe, Al, Co, Cu interact with fatty acid monolayers over the pH stability range of the basic metal ions. There were indications that the association could be influenced also by the size and shape of both the fatty acid molecule and the basic metal ionic unit. The present communication shows how these ideas can be applied to the chromium ionic system, together with a direct analogy between the interaction of the basic chromium ion, with fatty acid monolayers, and the tanning of a protein monolayer. Here, the reactivity of the carboxyl group is important in both systems.
