Abstract
The complex was obtained at room temperature: 10% water solution of SPI was mixed with 25% solution of vanadium salt (VOSO4×хH2O) in ratio 10:1 (in dry matter). The reaction was kept during 1 h at constant mixing with pH kept at 7.0- 7.1 with 1.0 M NaOH. The concentration of vanadium was determined in dry product by means of inductively coupled plasma mass-spectrometry. The chromatograms of SPI and V-SPI were obtained by means of size-exclusion high-pressure liquid chromatography, and then were integrated by weight method in the range of free till full column volume. The obtained complex of vanadium with SPI enzymatic hydrolysate (V-SPI) was water-soluble and contained 15.8 mg of vanadium per gram of product dry weight. Analysis of the molecular weight distribution of the peptide fractions of the original SPI enzymatic hydrolysate and the V-SPI complex showed that more than 87% of the vanadium complex was in peptide fractions with molecular weights more than 4.1 kD, including more than 75% of vanadium contained in fractions with molecular weights from 14.6 to 4.1 kD. The experimental evaluation in vivo will be the next stage of this research. The complex bioavailability and its effects on carbohydrate and lipid metabolism of Wistar rats with obesity will be evaluated.
