To the Editor.— The report on the value of the carotene absorption test as a measure of malabsorption and consequent steatorrhea by Onstad and Zieve that appeared inThe Journal(221:677, 1972) was a most welcome reminder of a useful but neglected procedure.

Carotene-Oxygen Radical Interactions
Free Radical Research Communications, 1992All-trans beta-carotene radical anion efficiently transfers an electron to oxygen but the reverse reaction is not observed and, instead we suggest the formation of a beta-carotene-superoxide radical addition complex. On the other hand, all-trans lycopene undergoes a reversible electron transfer with the superoxide radical.

Kuhn and Winterstein reported the isolation of 2,6-dimethylnaphthalene from the products of pyrolysis of carotenoid pigments. The production of alkyl derivatives of phenanthrene and chrysene by the same type of cyclization can readily be formulated.
