Compared to saturated fatty acids, unsaturated fatty acids a. have more hydrogen atoms b. tend to have a higher melting temperature c. are derived from animals d. are solids at room temperature e. are healthier for humans

The correct answer is E.

Explanation:

An unsaturated fatty acid has at least one double bond within the fatty acid chain.

They tend to have lower melting temperature than saturated fatty acids.

We can find them in oily fish, nuts and seeds, and vegetable oils.

They are liquid at room temperature.

These fats help reduce the risk of high blood cholesterol levels and therefore are healthier for humans.
