Answer:
A phospholipid is one of the major types of lipids; more specifically, it consists of two main components: a hydrophobic (water-fearing) tail and hydrophilic (water-loving) head. They are the main components of cell membranes, and their contrasting hydrophobic and hydrophilic subcomponents make them amphipathic molecules. Other major types of lipids include steroids and fats. :)
