Vitamin C and Hexuronic Acid

Nature, 1932
IN connexion with experiments under the direction of Dr. L. J. Harris1 on the ro1e of the suprarenal gland in vitamin C metabolism, we have investigated the silver nitrate staining capacity of glands taken from normal and scorbutic animals. It will be recalled that long before the identity of vitamin C with hexuronic acid was postulated2,3, Szent ...

Crystalline Structure of Hexuronic Acid

Nature, 1932
FROM a purified specimen of ‘hexuronic acid’ (identified by Szent-Gyorgyi with vitamin C) available in this laboratory I have been able to obtain sufficiently good crystals to carry out an X-ray examination by the single-crystal rotation method. The substance is monoclinic sphenoidal, with a = 17.71, b = 6.32, c = 6.38 A., and I² = 102½°, while the ...

Conversion of hexuronic acid to hexaric acid

The present invention relates to a method and microbial host strain for converting a hexuronic acid to a hexaric acid. In particular, the invention relates to the con-version of D-galacturonic acid to meso-galactaric acid (mucic acid). The invention also concerns an isolated nucleotide sequence.

Structural identification of isomeric O-trimethylsilyl derivatives of some hexuronic acids

Carbohydrate Research, 1977
The structures of the isomeric products obtained on trimethylsilylation of naturally occurring hexuronic acids and their sodium salts and lactones have been established by the application of n.m.r. (for anomeric configuration) and mass spectrometry (for ring size).
