ASCII depiction of the antioxidant enzyme defense system

Post by ianjager » Fri Sep 19, 2008 8:10 pm

Please forgive, but I lifted this abbreviated antioxidant enzyme
defense system (in ASCII form) scheme from Dr. Mark Kukucka's PhD
dissertation because I couldn't find anything else like it online!

that's actually not such a clear depiction if you ask me. When I originally learned this stuff from my Lehninger Biochemistry I understood it perfectly. From that, if I didn't know the material, I would have a pretty hard time.
