Waxes are the type of lipids responsible for waterproofing. They consist of long-chain fatty acids and alcohols, forming a water-repellent layer that helps prevent water loss and protects against dehydration.
A lipid wax is a type of lipid molecule that contains both fatty acids and long-chain alcohols. It is known for its water-repellent and protective properties, making it important for waterproofing and structural support in plants and animals. Lipid waxes commonly occur in the waxy coatings of leaves, fruits, and insect exoskeletons.

Phospholipids are the main lipid type that forms the foundation of cell membranes. They have a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails, which arrange themselves to create a lipid bilayer that encloses and protects the cell.
