Detailed explanation-1: -The amphipathic molecule has several hydrophilic and hydrophobic parts. Some of the examples of amphipathic molecules include bile salts, surfactants, and phospholipids. So, the correct answer is, ‘(c) Phospholipids’.
Detailed explanation-2: -All of the lipid molecules in cell membranes are amphipathic (or amphiphilic)-that is, they have a hydrophilic (“water-loving”) or polar end and a hydrophobic (“water-fearing”) or nonpolar end. The most abundant membrane lipids are the phospholipids. These have a polar head group and two hydrophobic hydrocarbon tails.
Detailed explanation-3: -A phospholipid is an amphipathic molecule which means it has both a hydrophobic and a hydrophilic component.
Detailed explanation-4: -Amphiphilic (amphiphatic): A molecule having both hydrophobic (nonpolar) and hydrophilic (polar) regions.
Detailed explanation-5: -An amphiphile (from the Greek amphis, both, and í philia, love, friendship), or amphipath, is a chemical compound possessing both hydrophilic (water-loving, polar) and lipophilic (fat-loving) properties. Such a compound is called amphiphilic or amphipathic.
