A key structural difference between triglycerides and phospholipids is that triglycerides are made up of three fatty acid chains attached to a glycerol molecule, while phospholipids have two fatty acid chains attached to glycerol, along with a phosphate group. This phosphate group makes phospholipids hydrophilic (water-attracting) on one end, while the fatty acid tails are hydrophobic (water-repelling), giving phospholipids a unique structure that is important for forming cellular membranes.
