The zinc-binding activity of different water-soluble pectin compounds varying according to their degree of esterification and of insoluble calcium pectate beads in aqueous solution was studied in a batch sorption system. The zinc uptake by all pectin compounds was highest within the pH range from 4.0 to 7.0. The binding capacities and rates of zinc ions by(More)
Cerium binding activity of different water soluble pectin compounds varying according to their degree of esterification and insoluble calcium pectate beads in aqueous solution was studied in a batch sorption system. The cerium uptake by all pectin compounds was highest within the pH range from 4.0 to 6.0. The binding capacities and rates of cerium ions by(More)
Carrageenans are abundant and safe non-starch polysaccharides exerting their biological effects in living organisms. Apart from their known pro-inflammation properties and some pharmacological activity, carrageenans can also strongly bind and hold metal ions. This property can be used for creation of the new drugs for elimination of metals from the body or(More)
In experiments on male white mice we initiated the induction of peroxidation of lipids by lead acetate, tetrachloromethane, sodium nitrite, or SOVOL (a mixture of polychlorinated biphenyls). Then the animals received intragastral injections of pectin isolated from the seagrass Zostera marina, in the form of a 1% gel, at 100 mg/kg for 2 weeks. It has been(More)
A comparative study of antioxidant activities of low-etherified pectin extracted from the eelgrass Zostera marina and of two antioxidative medicines, mildronat and emoxipin, was carried out using two in vitro methods allowing us to estimate the reducing activities of the compounds (FRAP assay), and their ability to impede iron- and ascorbate-induced(More)
The efficacy of an enterosorbent based on low-esterified pectin, activated charcoal, and polyphepan was evaluated in rats with experimental renal failure. Pectin was shown to be most effective. Its use causes increased daily diuresis and lower blood urine and creatinine levels in experimental animals. The findings have led to the conclusion that(More)
In this study, we determined the parameters of sorption of strontium ions by pectins that were isolated from the sea grasses Zostera marina and Phyllospadix iwatensis collected in the Peter the Great Bay of the Sea of Japan. The maximum strontium binding capacity and the coefficient of affinity with respect to strontium ions were significantly higher in sea(More)
