Question

Which describes the molecule below?

A. A lipid with three unsaturated fatty acids.
B. A lipid with two unsaturated fatty acids and one saturated fatty acid.
C. A lipid with two saturated fatty acids and one unsaturated fatty acid.
D. A lipid with three saturated fatty acids

Answer 1

A. A lipid with three unsaturated fatty acids.

Step-by-step explanation:

• The molecule above is a lipid, which is a triglyceride, that contains a glycerol backbone and three fatty acids.
• Unsaturated fatty acids are those fatty acids with either a double bond or triple bond in its structure. A fatty acid may be mono unsaturated or polysaturated where the double bond or the triple bond may occur more than once in its structure.
• In this case, the lipid has three unsaturated fatty acids, since all have one double bond in their structures.
