Making Usable, Quality Opaque or Transparent Soap Suzanne T. Mabrouk First-year and organic chemistry students will learn the chemistry of soap by making some of the eleven described formulations, which produce usable, quality bars of soap. Opaque and transparent soaps are made in two and three hours, respectively. With an introduction to formulation chemistry, organic chemistry students can devise a formulation to synthesize their own opaque soap. Many of the formulations use commonly-available fats and oils, while some formulations incorporate specialty fats and oils for therapeutic purposes, for example, to relieve dry skin or itching. Mabrouk, Suzanne T. J. Chem. Educ. 2005, 82, 1534.

Viscosity of Common Seed and Vegetable Oils C. Wes Fountain, Jeanne Jennings, Cheryl K. McKie, Patrice Oakman, Monty L. Fetterolf A viscosity experiment is presented here that is designed around common seed and vegetable oils. With the importance of viscosity to foodstuffs and the importance of fatty acids to nutrition, an experiment using these common, recognizable oils has broad appeal. Fountain, C.

Consequences of the lipid bilayer to membrane-associated reactions Eze, Michael O. The bilyaer is a very important component of the cell, and consequently fluidity changes within the liquid crystalline state, as well as changes from gel to liquid crystalline, must have profound effects on these membrane functions, and on functions that occur within the membrane.
