Triglycerides and phospholipids differ in structure. Triglycerides consist of three fatty acid chains connected to a glycerol molecule, while phospholipids have two fatty acid chains and a phosphate group attached to glycerol. The phosphate group makes one end of phospholipids attract water (hydrophilic), while the fatty acid tails repel water (hydrophobic). This unique structure is crucial for forming cell membranes.

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.
