Differential metabolism of cholesterol and sitosterol byPhytophthora cactorum

Abstract

When cultures ofPhytophthora cactorum grown on sterol-free medium were supplemented with a mixture of cholesterol and sitosterol, the sitosterol was initially taken up more rapidly than the cholesterol. Cholesterol was preferentially incorporated into the free sterol fraction and sitosterol into esters. More polar material was formed from sitosterol. Sitosterol is more active than cholesterol in promoting reproduction; this is attributed to the greater amount of polar metabolites formed from it.
