"WebThe phospholipid tail is pointed inwards because of its hydrophobic nature and associated with Vander Waal forces. If a phospholipid consists of a small tail, it forms a small lipid monolayer called “ Micelle ”. Conversely, a phospholipid molecule with bulkier tails forms a large lipid bilayer sphere called “ Liposome ”. " - Tail to tail bilayer
