Some of these are used as surfactants.
Degumming of plant oils is the removal of these specific molecules, which are used to build plasmalogens   in animal cells. The enzyme flippase moves these molecules from the inner to the outer surface, and it  is possible to scramble egg yolk into white because lecithin, one of these molecules, acts as a natural   emulsifier. Some of these are used as surfactants. When arranged in a single layer, these molecules  can form a micelle, but usually the hydrophilic heads points out while the hydrophobic tails point in,  forming a namesake bilayer. Name this type of lipid composed composed of fatty acids, glycerol, and  an anion, which makes up most of the cell membrane.
