WebOn the other hand, a sterol, named sterol Z, accounted for more than 50% of the total sterols in the cells grown in the presence of ethionine. As a result of experiments to raise the yield of sterol Z, the best concentration of DL-ethionine for the production was found to be 1.0 mM. The use of the methionine-less mutant was less effective for ... WebIn the subsequent steps of the pathway, six molecules of isopentenyl-pyrophosphate are used for the synthesis of one cholesterol molecule. Formation of a C 10 intermediate Squalene cyclization yields the first sterol intermediate. The reactions shown here are catalyzed by squalene epoxidase and lanosterol synthase.
