Oxalic Acid in Rhubarb Plant

Oxalic acid

Reproductive toxicology. Oxalic acid.

Background: We conducted an assessment of knowledge about blood borne pathogens (BBP) and use of universal precautions at first level care facilities (FLCF) in two districts of Pakistan. Methods: We conducted a cross-sectional survey and selected three different types of FLCFs ; public, general practitioners and unqualified practitioners through stratified random sampling technique. At each fac...

The Metabolism of Oxalic Acid*

103 Abstract: Oxalic acid is a widely occurring natural product of animals, plants and other organisms. It sometimes occurs as a free acid, but more commonly as a calcium salt. Organisms exhibit various levels of oxalate content which even show fluctuations among the organs of the same individual. Although oxalate seems to engage in the metabolism and adaptation of animals, plants and fungi, it...

13C chemical shielding in oxalic acid, oxalic acid dihydrate, and diammonium oxalate

13C chemical shielding tensors in three oxalates were investigated in order to determine the effe~ts of protonation and conformation changes on the tensor elements and their orientations. The expenmental results. together with those in the accompanying paper [R. G. Griffin and D. J. Ruben, J. Chern. ~hys. 63, 1272 (1975)], indicate that, while neither of these factors seems to seriously effect ...

Beeturia and colonic oxalic acid.

Beeturia is the excretion of red beetroot pigment (betalaine) in urine and faeces. It occurs in about 14% of humans. Betalaine is a redox indicator whose colour is protected by reducing agents. We investigated pigment-decolourizing systems in the intestinal tracts of beeturic and non-beeturic subjects. Betalaine was decolourized by hydrochloric acid, ferric ions and colonic bacteria preparation...
