Table 3 Relative energy content (heat of combustion)/carbon for TAG and starch

From: Comparative energetics and kinetics of autotrophic lipid and starch metabolism in chlorophytic microalgae: implications for biomass and biofuel production

  Energy
Mass for an equivalent number of moles of carbon (330) in TAG and starch  
6 moles TAG (C55H98O6) = 5124 g  
55 moles glucose in starch (C6H12O6, monomer) = 8928 g  
Energy content of an equivalent number of moles of carbon (330) in TAG and starch  
330 C = 5124 g TAG x 38 kJ/g TAG = 194,712 kJ/330C = 590 kJ/C
330 C = 8928 g starch x 15.5 kJ/g storage carbohydrate = 138,384 kJ/330C = 419 kJ/C
