How are lipid droplets formed
Web15 de nov. de 2002 · Lipid droplets were observed as round structures (Fig. 1, Band D); the content was of low electron density, but the rim was observed as a single electron-dense line of about 2–2.5 nm in width (Fig. 1 C).The result directly demonstrates that a single row of phosphorus atoms, or a phospholipid monolayer, covers the lipid droplet surface. Web1 de nov. de 2011 · Neutral lipids are stored in so-called lipid droplets, which are formed as small primordial droplets at microsomal membranes and increase in size by a fusion process. The fusion is catalyzed by the SNARE proteins SNAP23, syntaxin-5 and VAMP4. SNAP23 is involved in the insulin dependent translocation of GLUT4 to the plasma …
