Structure of Lipid Droplets:
Lipid droplets are organelles with a different structure form the rest of the endomembrane system. They consist of a netral lipid core surrounded by a single alyer of phospholipid. Neutral lipids are hydrophobic and include triglycerides and sterol lipids. These neutral lipids are made soluble in the aqueous cytosol by being coated with a phospholipid.
Functions:
Lipid drops form storage depots for lipids taht are used for energy metabolism, and to form membranes. Lipid droplets can also contain proteins involved in lipid syntehsis. This allows them to act as a seocndary site of lipid syntehsis.
