Which of the following is true regarding saturated fatty acids?

A) They are the predominant fatty acid in corn oil.

B) They have double bonds between carbon atoms of the fatty acids.

C) They are the principal molecules in lard and butter.

D) They are usually liquid at room temperature.

E) They are usually produced by plants.

C) They are the principal molecules in lard and butter.

Explanation:

Saturated fatty acids have only single bonds between their carbon atoms. The absence of double bonds make their breakdown more difficult hence they are more stable and can be stored for a longer time. They are also solid at room temperature.

Lard and butter are produced by hydrogenation of oils. The double bonds in oil are broken into single bonds and valency is completed using hydrogen atoms. Hence lard and butter consist of single bond saturated fatty acids

C) They are the principal molecules in lard and butter.
