MCAT Question of the Day
    •

    Q:

    		 Scientists have identified the compound tryptophol to be a derivative of the amino acid tryptophan. Tryptophol induces drowsiness in humans, and a student concludes based on this information that consumption of tryptophan will induce sleep in humans through the production of tryptophol. Is the student correct in this conclusion, and why or why not?
    		 

    A

    		 Yes, because tryptophol is a derivative of tryptophan and therefore it will be produced when tryptophan is consumed.

    B

    		 Yes, because tryptophol is produced regardless of the presence of tryptophan.

    C

    		 No, because humans tryptophan is not absorbed and will be excreted regardless of the production of tryptophol.

    D

    		 No, because humans might lack the necessary enzymes to catalyze the conversion of tryptophan to tryptophol.
