Lipid distribution of animal cells. In animal cells, lipids are distributed in the plasma membrane (PM) and intracellular organelles. In all membranes, most commonly found lipids are phosphatidylcholines (PC) followed by phosphatidylethanolamines (PE). Cardiolipin is prevalently found in mitochondria. Extra FAs and free cholesterols are esterified in the ER and stored within cytosolic lipid droplet (LD) as triacylglycerol (TG) and cholesterol ester (CE) respectively. Lipid rafts are concentrated with cholesterols and sphingolipids
