Influence of silver ions on permeability through biomembranes of humic substances in peloids

In work possibility of penetration the humic substances and their derivatives through biological membranes is shown. It is shown that permeability depends on acidity of the environment and presence of transagents. Bioavailability of the studied peloids preparations increases in slightly alkaline and decreases in acidic environment that is connected with changes of spatial configuration of macromolecules.
