Question

the diagram shows a type of lipid. which type of lipid is shown? a saturated phospholipid a saturated triglyceride an unsaturated phospholipid an unsaturated triglyceride

Explanation:

• Phospholipids have a phosphate - containing head (the blue part in the diagram) and fatty acid tails (the long chains). Triglycerides do not have a phosphate group.
• Saturated fatty acids have no double bonds (the tails are straight as in the diagram). Unsaturated fatty acids have double bonds which would cause kinks in the tails.

Answer:

a saturated phospholipid
