WebOct 1, 2024 · The exoplasmic PM leaflet of a cell might sometimes phase separate into Ld + Lo phases, whereas the lipid composition of the cytoplasmic leaflet, with almost no high Tm lipids and with a high fraction of PUFAs, is expected by inference to form a fluid leaflet, and is so observed in studies of symmetric model membranes [12]. WebAug 15, 2024 · Background The transbilayer sterol distribution between both plasma membrane (PM) leaflets has long been debated. Recent studies in mammalian cells and in yeast show that the majority of sterol resides in the inner PM leaflet. Since sterol flip-flop in model membranes is rapid and energy-independent, a mechanistic understanding for net … poppies and war photographer comparison essay
