Chemistry Everyday For Everyone
Applications and Analogies
Musk Oxen and Micelles
John W. Hill
University of Wisconsin-River Falls, River Falls, WI 54022

September 1996
Vol. 73 No. 9
p. 847
Abstract
Musk oxen behavior provides an analogy to micelle formation by amphipathic substances. Mature male musk oxen protect their young and females from wolves by forming a protective circle around them. The males stand with their tails to the inside and their heads facing outward. Amphipathic substances such as soap form micelles. The hydrophobic hydrocarbon tails of the soap are turned to the inside of the micelle and the hydrophilic carboxylate heads are on the outside at the interface with the polar water molecules.
