Question

Which of the following is the best definition of a saturated fatty acid?

A. An insoluble compound made up of glycerol and three fatty acids
B. A basic unit of a lipid that consists of single and double carbon-to-
carbon bonds

C. A basic unit of a lipid that consists of only single carbon-to-carbon
bonds

D. A compound that carries hereditary information

Answer 1

The correct answer is C

Answer 2

The best choice would be C.

A saturated fatty acid is a basic unit of lipid that consists of only single carbon to carbon bonds.

Saturated fatty acids have been “saturated” with hydrogen ions and only have single carbon to carbon bonds, unlike unsaturated fatty acids that have both single and double bonds and have kinks and aren’t straight.

Saturated fatty acids are solid in room temperature(animal fats) and unsaturated fatty acids are liquid in room temperature(oils/plant fats).
