Saturated fatty acids predominate in which of the following lipids?
A
Corn oil
B
Butter
C
Olive oil
D
Fish oil
Verified step by step guidance1
Understand the concept of saturated fatty acids: Saturated fatty acids are fatty acids that lack double bonds between carbon atoms in their hydrocarbon chains. This makes them solid at room temperature due to their tightly packed structure.
Identify the lipid types: Corn oil, olive oil, and fish oil are primarily composed of unsaturated fatty acids, which contain one or more double bonds in their hydrocarbon chains. These double bonds create kinks in the structure, making them liquid at room temperature.
Recognize the lipid associated with saturated fatty acids: Butter is rich in saturated fatty acids, which contribute to its solid state at room temperature. This is due to the absence of double bonds in the fatty acid chains, allowing for tight packing of molecules.
Compare the physical properties of the lipids: Saturated fatty acids in butter result in a solid texture, while unsaturated fatty acids in corn oil, olive oil, and fish oil result in liquid textures at room temperature.
Conclude the relationship: Saturated fatty acids predominate in butter, making it the correct answer to the question.
