The location of tritium in [1-3H]ergosterol
Abstract
Tritium in [1-3H]ergosterol has been found to be distributed 83–85% at the 1α- and 13–15% at the 1β-position. It has been confirmed that the tritium at the 2-position is lost during enol acetylation of [1,2-3H2]ergosta-4,6,22-trien-3-one. A comparison with other 1- and 1,2-tritiated steroids is given.
