Question

multiple choice question
a fatty acid has a double bond in its carbon chain. it is a(n) ________ fatty acid.
o lipid
o polyunsaturated
o saturated
o unsaturated

Explanation:

Fatty acids are classified based on the presence of double - bonds in their carbon chains. Saturated fatty acids have only single bonds. Unsaturated fatty acids have one or more double bonds. If there is just one double bond, it is monounsaturated. If there are multiple double bonds, it is polyunsaturated. Since the question only mentions a double bond (not specifying multiple), it is an unsaturated fatty acid. Lipid is a broader category that includes fatty acids.

Answer:

O unsaturated
