Question

Which of the following is TRUE concerning unsaturated fatty acids?

-They are usually solid at room temperature.
-Their chains are usually straight.
-They have a lower ratio of Hydrogen to Carbon than saturated fatty acids.
-They have no double bonds between the carbon atoms of the fatty acids.

Answer 1

Unsaturated fatty acids have a lower ratio of Hydrogen to Carbon than saturated fatty acids, and they contain double bonds between the carbon atoms of the fatty acids.

Step-by-step explanation:

Unsaturated fatty acids have a lower ratio of Hydrogen to Carbon than saturated fatty acids. They contain one or more double bonds between the carbon atoms of the fatty acids, which causes a bend or a 'kink' in the carbon chain. This prevents the fatty acids from packing tightly, keeping them liquid at room temperature. Olive oil, corn oil, canola oil, and cod liver oil are examples of unsaturated fats.
