CHARACTERIZATION OF OXALIC ACID IN VEGETABLES

Oxalic Acids in Vegetables Determination of Free and

Vegetables generally contain more or less oxalic acid, which is produced by metabolism in cytoplasm.12 Most of the oxalic acid is fixed as calcium oxalate to protect protoplasm from its toxic action.3 Vegetables containing a considerable quantity of oxalic acid are usually boiled before being cooked to remove any harshness.4 The oxalic acid contained in food is determined by the KMnO4 titration...

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...

The effect of sulfuric acid on pore initiation in anodic alumina formed in oxalic acid

In this work, a tracer study on pore initiation in anodic alumina in oxalic acid was performed. Effects of some experimental parameters such as applied electrical potential, electrolyte composition and heat pretreatment were evaluated. Electrochemical and morphological experiments were performed using potentiostatic anodizing and scanning electron microscopy (SEM) techniques, respectively. Effe...

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...
