Mineral ascorbates are salts of ascorbic acid (aka vitamin C). They are powders manufactured by reacting ascorbic acid with mineral carbonates in aqueous solutions, venting the carbon dioxide, drying the reaction product, and then milling the dried product to the desired particle size.
The choice of the mineral carbonates can be calcium carbonate, potassium carbonate, sodium bicarbonate, magnesium carbonate, or many other mineral forms. Ascorbates are highly reactive antioxidants used as food preservatives.
Ascorbate salts may be better tolerated than the corresponding weakly acidic ascorbic acid.
The treatment of a neurotic patient was interrupted because of nausea and regurgitation. In pregnant women, the incidence of pyrolysis and chronic constipation is slightly increased. In children, a clinical investigator reported 3 cases of slight diarrhea which disappeared within a few days. In 1 case, slightly curdled stools were observed, although this could not be definitely attributed to the product. In the final case studies, clay colored stools were noted.
In vitro generation of thiobarbituric acid reactive substances (TBARS) is frequently used to assess organ susceptibility to lipid peroxidation. The yield of TBARS is severalfold enhanced by an addition of iron ions with reductors or chelators such as ascorbate, NADPH, ADP or pyrophosphate. The process cannot be interpreted in a simple way, since it involves several enzymatic and nonenzymatic reactions. There are no clear interpretations of the ambiguous effects of denaturating factors and chelating agents on TBARS generation. Also controversy arises from the curvilinear relationship between the homogenate concentration and the yield of TBARS. This has been modelled in the present work by combining two functions describing the sequential reaction with two limiting steps. One of them is related to catalytic action of iron and ascorbate, while the other to an enzyme, possibly phospholipase A2, as has been suggested by some investigators. Two models should be considered since it is impossible to decide which kinetic equation should predominate in the model. Nevertheless, the model reflects kinetic properties of the process. The effects of catalyst concentration and some other modification upon the yield of TBARS were also investigated experimentally. The results of experiments and modelling showed that the analytical procedures used by investigators need standardisation as the results obtained under a variety of procedures may reflect quite different properties of the living systems.
Biocare nutrisorb zinc ascorbate. Zinc, like most minerals is efficiently chelated to ascorbic acid and has an efficient absorption rate so that small amounts provide effective supplementation. 30ml of bottle available. Suitable for childrens, vegetarians.
