— The use of cyclic 1,3‐dienes and polycyclic aromatic hydrocarbons as xenobiotic substrates for the interception of electronically excited (singlet) molecular oxygen ( 1 O 2 ) in biological systems is reviewed and criticized, and the possibility of utilization of reactive endogenous substrates for 1 O 2 interception is considered. The common sterols, cholesterol, 5α‐cholest‐7‐en‐3β‐ol, and 5α‐lanost‐8‐en‐3β‐ol each give oxidation products with 1 O 2 different from those with ground‐state molecular oxygen that can be distinguished from one another by simple chromatographic means.
