Abstract
SOME years ago, Prof. Robinson1 put forward in these columns the ingenious suggestion that the conversion of glucose into galactose in the organism is a direct one and due to an inversion of the configuration of the groups attached to the fourth carbon atom of the glucose molecule, consequent upon esterification of the hydroxyl group concerned by phosphoric acid. It is, however, now recognised that the terminal carbon atoms, as distinct from the fourth carbon atom, are those which are esterified in the fructose di-phosphoric acid involved in biological processes, and that in these latter the acid suffers disruption into the phosphoric esters of d-glyceric aldehyde and dihydroxy acetone.
