Now this is a story all about how catabolism of carbohydrates pans out I’d like to take a minute, just hear me say, I’ll tell you how glycolysis turns glucose to pyruvate In the glycolytic pathway, where we be. With glucose attacking phosphorus in ATP Chillin’ out, maxin’, relaxin’, with Mg. Forming glucose-6-phosphate and ADP When step number 2 comes along, isomerization is the bomb! One little change is what Bruice meant, she said, “it’s kinda like an ene-diol rearrangement” I studied step 3, and then day after day, I realized it’s the mech. in step one, and went “Hey!” Give me step 4, I thought, “aldol-addition, add it!” I put my thinking cap on and said, “better reverse it!” Third class, yo this is rad. Did some of these reactions in my lab. Is this what CHEM109C be like? Hmm, UCSB might be alright! But I hear they’re prissy, IV, all that. Is this the type of place they just send this lab rat? I don’t think so, let’s move on to step 5. Dihydroxyacetone to glyceraldehyde! Well this mechanism is a little tough. It’s got a glutamate, a histidine, and lots of stuff. I might not understand it yet, but hey, I just got here! So, I studied the book ’til daylight disappeared Moved on to step 6, oxidized with NAD. Formed a carbo. acid then bisphospho-1,3, If anything, I could say step 7 is rare. Exergonic reactions are sick, “Yo homes, coupled pairs!” I end the glycolytic pathway with steps 8 and 9, and I do an isomerization, “Yo homes, dehydration!” I look at my notes, and I’m finally done. Bout to learn glycolysis with a rap that is fun!
