[Micro method for the selective assay of unesterified long chain fatty acids in serum (author's transl)].

Abstract

A microanalytical method is reported for the selective and direct determination of low concentrations of unesterified fatty acids in serum. A new procedure is used to form derivatives of the fatty acids with alkyl iodide, which are separated over a solid phase of K2CO3. The assay was developed for the qualitative and quantitative determination of unesterified fatty acids mobilized from fat tissue in defined metabolic states.
