Answer #1

PHOSPHOLIPID:-
-Phospholipids are a class of lipids that are a major component of all cell membranes. They can form lipid bilayers because of their amphiphilic characteristic.
- phospholipid molecule consists of two hydrophobic fatty acid "tails" and a hydrophilic "head" consisting of a phosphate group
-Example - phophatydilcholine
- Chemical structure-RIACYLGLYCEROL:-
- A triglyceride is an ester derived from glycerol and three fatty acids.
-Triacylglycerols are not found in cell membranes because they are not amphipathic.
