Lipid droplets bud off the membrane of the endoplasmic reticulum. Initially, a lens is formed by accumulation of TAGs between the two layers of its phospholipid membrane. Nascent lipid droplets may grow by diffusion of fatty acids, endocytosis of sterols, or fusion of smaller lipid droplets through the aid of SNARE proteins. The budding of lipid droplets is promoted by an asymmetric accumulation of phospholipids that decrease surface tension towards the cytosol.
