Phenylalanine & tyrosine
           degradation

   Degradation of phenylalanine
starts with conversion to tyrosine

        catalyzed by phenylalanine
               hydroxylase.

      Fumarate & acetoacetate
                    are formed.

        Fumarate is converted
              to oxaloacetate
                for TCA cycle
             & acetoacetate is

      converted to acetyl CoA.
