Vaporization of a ornithine‐containing polar lipid from Thiobacillus thiooxidans has been accomplished by thermolysis in a chemical ionization source. The thermolysis has been shown to be more extensive than previously thought. It occurs in at least two steps, the first being dehydration of the ornithine to produce a substituted piperidone. This fragment undergoes a facile elimination to produce two neutral lipid components: a long chain fatty acid and piperidone‐containing fatty amide. The results demonstrate the utility of chemical ionization for developing an understanding of a thermolysis process.
