Ketohexokinase, isoenzymes of glucokinase and glycogen synthesis from hexoses in neonatal rat liver

Abstract

PURIFICATION OF CHORISMIC ACID 261 tion of the structure shown for chorismic acid was obtained by examination of a deuterium oxide solution of barium chorismate by nuclear-magneticresonance spectroscopy (Gibson & Jackman, 1963). Chorismic acid can be formulated as the 3-enol- pyruvic ether of tran8-3,4-dihydroxycyclohexa-1,5dienecarboxylic acid. SUMMARY 1. Chorismic acid, a new intermediate in aromatic biosynthesis, is the 3-enolpyruvic ether of trans-3,4-dihydroxycyclohexa-1 ,5-dienecarboxylic acid.
