The existence of two interconvertible forms of 18-hydroxycorticosterone: Is one of them an active pŕecursor of aldosterone?
18-Hydroxycorticosterone exhibits a spontaneous interconversion between two forms separable by paper chromatography, a and b. Upon acetylation, both give rise to at least one compound having identical chromatographic properties irrespective of the basic form utilized. Both forms present different ch...
