Reaction between glucuronolactone and glucuronic acid was examined.
1) There is an equilibrium between glucuronolactone and glucuronic acid.
2) This reaction occurs in hydrochloric acid solution by pseudo-first order reaction and is found to be first order with respect to both hydrogen ion and-the lactone or the acid.
3) The thermochemical equation between these lactone and acid can be shown by:
C6H8O6+H2O⇔C6H10O7+4.7 kcal.
