A method for the collection and measurement of low-molecular-weight volatile hydrocarbons
exhaled in human breath as a result of lipid peroxidation in vivo is described. Subjects …

The straight chain aliphatic hydrocarbons ethane and pentane have been advocated as
noninvasive markers of free-radical induced lipid peroxidation in humans. In in vitro studies …

Numerous studies in animals and humans provide evidence that ethane and pentane in
expired air are useful markers of in vivo lipid peroxidation. The measurement of breath …

Monitoring of ethane and pentane in breath as a noninvasive method to measure lipid
peroxidation is performed by an increasing number of laboratories. The alkanes are …

A simple method is described for concentrating ethane from large volumes of air; the
sensitivity limits for detecting exhaled ethane are increased by 100-fold or more. The method …

Publisher Summary Volatile hydrocarbons, such as ethane and pentane, are known to
originate from the peroxidation of polyunsaturated fatty acids present in membrane lipids …

Lipid peroxidation is suspected of being involved in a number of pathological processes.
Proof of this has been very difficult to obtain, however. A major problem has been the lack of …

Publisher Summary The measurement of exhaled hydrocarbons has evoked widespread
interest in recent years as a noninvasive method for monitoring in vivo lipid peroxidation …

Lipid peroxidation occurs in animal tissue when antioxidant protective systems are lacking.
Among the protective systems in animals are the biological antioxidant vitamin E and …

Publisher Summary Research in food chemistry provided the basis of a new technique for
the measurement of lipid peroxidation in living animals by quantitative gas chromatographic …
