An example is the mobilization of soil phosphate by excretion of particular organic anions.
Analysis of anions leached from rock samples suggests that subsurface pyrite weathering is centered at two zones within the ore body.
Uptake by either transporters or coupled cation plus anion uptake on separate channels might then be followed by diffusion and dilution within the syncytium.
Neutrophil-derived superoxide anion induces lipid peroxidation and stimulates collagen synthesis in human hepatic stellate cells : role of nitric oxide.
This is a complex form of the anomalous mole fraction effect - one that effectively involves different affinities for anions and cations.
The information on selectivity among cations or among anions is sparse, but intriguing.
A number of specific transport proteins are located in biliary epithelia, including anion exchangers and water transporters (for a review see ref. 41).
The binding of some small anions to serum albumin.
