Bickeldefines the political question doctrine, in the passage quoted in sec-tion I, in terms of the Court's sense of unease at straying into thedecision of difficult and delicate questions involving the separationof powers and requiring political expertise or sensitivity to makean intelligent decision.
A chelate is a chemical compound composed of a metal ion and a chelating agent. A chelating agent is a substance whose molecules can form several bonds to a single metal ion. In other words, a chelating agent is a multidentate ligand. An example of a simple chelating agent is ethylenediamine.ethylenediamine. A single molecule of ethylenediamine can form two bonds to a transition-metal ion such as nickel(II), Ni 2+ .n other words, a chelating agent is a multidentate ligand.

Mineral supplements provided as chelated minerals have dramatically improved absorptions over minerals supplements provided as simple mineral salts like zinc chloride. Heres why... Chelation is literally the protective enclosure of a mineral like zinc or iron within amino or other natural organic acids.he safety and performance chelated minerals is well-established fact. Minerals chelated within amino acids or fulvic acids (colloidal minerals) provide superior absorption and help protect you from unbalanced absorption that can occur with simple mineral salts.
