The critical micelle concentration of some physiologically important fatty acyl-coenzyme A's as a function of chain
Abstract:
The critical micelle concentration (CMC) of a series of saturated fatty acyl-CoAs have been determined using a fluorescent titration method with 2-toluidinylnaphthalene-6-sulfonate as a probe. The CMC was found to be a function of the number of carbon atoms in the acyl chain over the range tested (12 to 18). A double bond has the effect on the CMC of decreasing the acyl chain by 1.6 carbon atoms. Knowledge that the CMC of each of these fatty acyl-CoAs is a function of the acyl chain length and the availability of a simple and appropriate method for the estimation of this property under other conditions should be of importance in designing and interpreting in vitro experiments with these compounds.

Overview of Fatty Acid Metabolism
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...
