Question

You look at the label on a container of shortening and see "hydrogenated vegetable oil." This means that during processing the number of carbon-carbon double bonds in the oil was decreased. What is the result of decreasing the number of double bonds?

            A)  The oil is now a liquid at room temperature.

            B)   The oil is now a solid at room temperature.

            C)   There are more "kinks" in the fatty acid chains.

            D)  The oil is now a derivative carbohydrate.

            E)   The fatty acid is now a triglyceride.
