Lipid dynamics in yeast under haem-induced unsaturated fatty acid and/or sterol depletion.

In the yeast Saccharomyces cerevisiae, UFA (unsaturated fatty acids) and ergosterol syntheses are aerobic processes that require haem. We took advantage of a strain affected in haem synthesis ( hem1 Delta) to starve specifically for one or the other of these essential lipids in order to examine the consequences on the overall lipid composition. Our results… CONTINUE READING
