How do phospholipids differ from fats? Phospholipids have two fatty acids while fats have three. Phospholipids have phosphate groups while fats do not. Phospholipids do not contain a glyceride molecule while fats do. Phospholipids are water-soluble while fats are not soluble in water.

Which of the following statements is true of phospholipids and triglycerides: Triglycerides are composed of three fatty acids bonded to glycerol backbone. Phospholipids are phosphate head that is bonded directly to two fatty acids. Triglycerides are always associated with cell membranes; they provide flexibility. Phospholipids are composed of a phosphate group bonded to glycerol backbone and two random side groups. Phospholipids and triglycerides are not the same molecules.

This is a triglyceride (fat molecule). Three fatty acids (lipids) are linked to a glycerol molecule. Which of the following are true? (Mark all correct answers) The bottom carbon chain is unsaturated. It is a carbohydrate. The lipid portion of the molecule is non-polar. The glycerol portion of the molecule is non-polar. The bottom carbon chain is saturated.
