1 Glycerol 3-phosphate - a hydroxy ester; low energy

2 Resonance forms

3 A pyrophosphate

4 High-energy phosphates

5 Free energies of hydrolysis of several phosphates

6 Source of energy in an organism versus time of use.

7 ATP supplies energy for the pink and is made by the blue reactions.

8 Most reduced structure has most energy. Oxidation harvests the energy.

9 Fatty acid has lots of calories; glucose has less - already more oxidized.

10 A regular compound energetically

11 Chemiosmotic separation of protons provides the energy for oxidative phosphorylation.

12 Catabolism of polymer to simple unit of acetyl~CoA then complete oxidation and oxidative phosphorylation.

13 Energy charge = [ATP] + 0.5 [ADP]/[ATP] + [ADP] + [AMP]
How much is “charged” in the ATP form.

14 ATP

15 Chemical Sense in Metabolism
Lecture 25 Chemical Sense in Metabolism Chemical sense is important. Biochemicals follow the laws of chemistry.
