Final answer:
The most abundant lipid of the membrane consists of a head and two tails. This type of lipid is a phospholipid.
Step-by-step explanation:
The most abundant lipid of the membrane consists of a head and two tails. This type of lipid is a phospholipid. Phospholipids are a major component of cell membranes and have a hydrophilic head and a hydrophobic tail. These properties allow phospholipids to form a two-layer cell membrane called a lipid bilayer.
