Wait you guys didn't memorize this chart? What kind of doctors are you guys going to be?!?!?! Failures.....
So from what I've heard, know enzymes ONLY if they are associated with a disease (glucocerebrosidase in Gauchers) OR if they are the rate limiting enzyme of a reaction (CPT-1 in FA synthesis or HMG-CoA reductase in cholesterol synthesis), etc etc etc.
Otherwise...who cares?
