In the currently accepted theories on membrane protein crystallization, discussed above, the only role of the detergent is to stabilize the membrane protein in aqueous solution. However, the effect of detergent structure on the crystallization of bovine heart cytochrome c oxidase.

A large variety of chemical structures that can be classified as detergents have been used in lubricants. In this section, we will review the basics of the most common detergent structures and the chemistry of their production.

During the process of absorption, cholesterol dissolved in the lipid core of micelles is transported from the lumen of the small intestine across the intestinal wall and into the lymph. Because the solubility of cholesterol in aqueous systems is low, its absorption depends on the formation of detergent structures (mixed micelles) in the small intestine. These are composed mainly of bile salts, phospholipids, digestion products of fats such as fatty acids and monoacylglycerols, cholesterol (of which 90% is in free form), and fat-soluble micronutrients (Figure 6). 

Figures illustrate the effect of non-ionic detergents on the activity of a range of antibiotics, showing the effect of concentration and of detergent structure on chloramphenicol activity as shown by zone-inhibition assay. Whether this mode of assay bears any relationship to actual conditions in vivo is a matter for debate. See also Ullmann and Moser [173].
