A gas chromatographic method for the quantitative detemination of hexuronic acids in alginic acid

Analytical Biochemistry, 1981
Abstract A method has been developed for the quantitative determination of the relative proportions of d -mannuronic and l -guluronic acids in alginic acid. To obtain homogeneous reaction conditions the viscosity of the alginic acid sample was first decreased by limited hydrolysis with mineral acid.

Engineering hexuronic acid catabolism

2014
A engenharia metabólica é uma área emergente que visa o aperfeiçoamento de vias metabólicas para produção de compostos valiosos. A produção mundial de casca de frutos cítricos é estimada em 15,000,000 de toneladas por ano, e o seu descarte causa problemas ambientais. O principal constituinte da casca de frutos cítricos é o ácido D-galacturónico.

HEXURONIC ACID, HEXOSAMINE, AND RADIOSULPHATE UPTAKE IN OVARIES OF MYXOEDEMATOUS RABBITS

Acta Endocrinologica, 1962
ABSTRACT One month after radical surgical thyroidectomy, 13 out of 28 rabbits had raspberry-like polycystic ovaries. Thyroidectomy increased the content of water, hexuronic acid, and the in vivo uptake of 35S-labeled sulphate in acid mucopolysaccharides.
