How are lipid droplets formed
Web1 de fev. de 2024 · Lipid droplets (LDs) are ubiquitous intracellular organelles that consist of a core of neutral lipids (NLs), mostly triglycerides (TG) and sterol esters, surrounded by a phospholipid (PL) monolayer (Walther and Farese, 2012).Because of this unique composition, they are the cellular sites responsible for energy and lipid storage and they … Web18 de mar. de 2010 · Lipid droplets (LDs) ... A spatial restriction of the LD biogenesis machinery within the ER is in line with the current model of how LDs are formed, since the accumulating neutral lipid in the ER intermembrane space would otherwise eventually spread further in the hydrophobic environment instead of nucleating the proposed LD “lens”.
