Question

name a structural difference between triglycerides and phospholipids.

Explanation:

Triglycerides have three fatty - acid chains attached to glycerol, while phospholipids have two fatty - acid chains and a phosphate group attached to glycerol. The phosphate group in phospholipids gives them a polar head, making them amphipathic, which is important for cell - membrane structure. Triglycerides are non - polar and mainly used for energy storage.

Answer:

Triglycerides have three fatty - acid tails attached to glycerol, while phospholipids have two fatty - acid tails and a phosphate - containing head group attached to glycerol.
