MCAT Question of the Day
    •

    Q:

    		 Trans fats, as opposed to cis fats, are commonly produced when chemically hydrogenating fatty acid chains, but are rarely produced enzymatically. Which of the following best explains the discrepancy?
    		 

    A

    		 Chemical hydrogenation occurs at higher temperatures which allows for production of trans fats that cannot form a physiological temperatures.

    B

    		 Enzymatic hydrogenation occurs in aqueous solution which prevents the formation of trans fats, whereas chemical hydrogenation can use non-aqueous solvents.

    C

    		 Synthetic modification of foods leads to the production of unexpected compounds.

    D

    		 The hydrogenating enzymes are stereospecific.
