The 2- and 3-glyceroyl esters were found to be ‘energy-rich' with δG°' values of −9.1 kcal mol−1 and −7.8 kcal mol, respectively. This result indicates that the analogous 2- and 3-glyceroyl esters of polyglyceric acid are also ‘energy-rich' and, therefore, could have acted as an energy source for primitive phosphoanhydride synthesis.
