Question

ter, wensenester Donas to produce glycerol and three molecules of stearic acid. 7. Describe the similarities and differences between triacylglycerols and glycerophospholipids.

Answer 1

Glycerophospholips contain phosphate groups in their fatty acid chains. A triacylglycerol has ester groups with three fatty acid chains.

triacylglycerols are the storage forms of fatty acids and glycerophospholipids are compnents of biological membranes.

Triglycerides have glycerol and three fatty acids, which makes them fats. Phospholipids are not fats, since they have glycerol, two fatty acids and phosphorus. Phospholipids are more essential to the formation of lipid bilayers, which maintain cell membrane structure, than triglycerides are. Fat cells store triglycerides, while phospholipids help break down fats in the body.

phospholipids have a more rigid chemical structure than triglycerides do, so they make cell membranes tougher and help them to hold their shape better than triglycerides alone could.

Most animals, including humans, can make enough phospholipids on their own that they do not need to seek out phospholipids in food. This is not the case with triglycerides, which are an essential nutrient, and make up the bulk of an animal's fat intake.
