TL;DR: Subcellular membranes of Saccharomyces cerevisiae, including mitochondria, microsomes, plasma membranes, secretory vesicles, vacuoles, nuclear membranes, peroxisomes, and lipid particles, were isolated by improved procedures and analyzed for their lipid composition and their capacity to synthesize phospholipids and to catalyze sterol delta 24-methylation.

TL;DR: Organelles of the yeast Saccharomyces cerevisiae were isolated and analyzed for sterol composition and the activity of three enzymes involved in sterol metabolism, leading to the view that ergosteryl esters of lipid particles might serve as intermediates for the supply of ergosterol from internal membranes to the plasma membrane.

TL;DR: In lipid particles of the yeast mutant strain S. cerevisiae erg6, this protein is missing thereby identifying the protein and confirming the previous finding (Zinser et al., 1993) that sterol Δ24‐methylation is associated with lipid particles.

TL;DR: Evidence is presented that certain enzymes of phospholipid biosynthesis are enriched in a special microsomal fraction associated with mitochondria, which is named MAM, which can be readily imported into mitochondria and converted to phosphatidylethanolamine.

TL;DR: A possible function of plasmalogens as antioxidants has been demonstrated with cultured cells and might play a role in serum lipoproteins.
