glyphosate in northern ecosystems

Glyphosate

Glyphosate is an aminophosphonic analogue of the natural amino acid glycine and like all amino acids exists in different ionic states depending on pH Both the phosphonic acid and carboxylic acid moieties can be ionised and the amine group can be protonated and the substance exists as a series of zwitterions Glyphosate is soluble in water to 12 g/l at room temperature
