Explanation:
Detailed explanation-1: -The most abundant membrane lipids are the phospholipids. These have a polar head group and two hydrophobic hydrocarbon tails.
Detailed explanation-2: -Each phospholipid is amphipathic, with two hydrophobic tails and a hydrophilic head. The hydrophobic tails face inward towards one another, and the hydrophilic heads face outwards.
Detailed explanation-3: -A hydrophobic tail is a hydrocarbon chain consisting of carbon and hydrogen atoms. It is an organic chain. It is composed of water-fearing fatty acid chains that restrict the movement of water molecules across the cell membrane. Molecules consisting of fatty acids are known to have hydrophobic tails.
