What is the difference between a saturated and an unsaturated fatty acid?

Answer and explanation

Correct answer: C. Saturated fatty acids have no carbon-carbon double bonds in the hydrocarbon tail

  1. Step 1: The tail of a saturated fatty acid has only single bonds, so it holds the maximum number of hydrogen atoms. Step 2. Unsaturated tails contain one or more C=C bonds. Answer: Saturated fatty acids have no carbon-carbon double bonds in the hydrocarbon tail. Why not the others: that statement describes unsaturated; unsaturated tails still contain hydrogen atoms; phosphate groups are found in phospholipid heads.
