Pentane and isoprene in expired air from humans: gas-chromatographic analysis of single breath
S Mendis, PA Sobotka, DE Euler - Clinical Chemistry, 1994 - academic.oup.com
Both pentane and isoprene are excreted in human breath. Although pentane is considered
an index of lipid peroxidation, the significance of isoprene is unknown. Having a similar …
