Ever since, this reaction has been a major tool of steroid chemists; it has been used in many methods for cholesterol determination and in many separations of steroids with the beta ...
متن کاملPhylogenetic Distribution of Fungal Sterols
BACKGROUND Ergosterol has been considered the "fungal sterol" for almost 125 years; however, additional sterol data superimposed on a recent molecular phylogeny of kingdom Fungi reveals a different and more complex situation. METHODOLOGY/PRINCIPAL FINDINGS The interpretation of sterol distribution data in a modern phylogenetic context indicates that there is a clear trend from cholesterol and...
