Hence, the process was exergonic and would have proceeded spontaneously in the forward direction to form the product.
It is a highly exergonic reaction driving biosynthetic reactions, such as NA synthesis and lipid synthesis and degradation.
It can be observed that the HAT mechanism towards OR; radicals is exergonic except for reactions towards O[R.sub.3] (J14 ([DELTA]G = 0), J15 ([DELTA]G = 531 kJ/mol), J17 ([DELTA]G = 11 kJ/mol), and J18 ([DELTA]G = 3 kJ/mol)) and that towards O[R.sub.4] (J15 ([DELTA]G = 511 kJ/mol) and J18 ([DELTA]G = 1 kJ/mol)) and that towards O[R.sub.2] (J18 ([DELTA]G = 38 kJ/mol)).
When proximity of matter is increased, as in the condensation of molecules onto grains, endergonic or exergonic reactions can occur and will increase organic molecular complexity with compounds of dozens or even hundreds of atoms.
