Glucose vs Fatty Acid in Energy

Postby rosegarden » Mon Feb 21, 2011 6:15 am

Hi guys

I'm wondering which would release more energy by combustion, a mole of glucose(C6H12O6) or a mole of hexanoic acid (C6H12O2)? And also, which of the two will produce more ATP?

My idea is that glucose is more oxidized thus it has lower free energy so it probably doesn't release as much energy as hexanoic acid. As for production of ATP, again the hexanoic acid being the more generous electron donor should result in more ATP?

you're rigth, the carbons in Glc are already partly oxidized and thus the released energy will be smaller in both cases.

Cis or trans? That's what matters.
