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.

When zinc is combined with amino acids or other organic acids, the result is a zinc chelate. The chelating agent boosts the amount of zinc absorbed into your system, which is important because zinc helps produce proteins and supports the immune system.inc chelates are made by attaching zinc to two groups of organic substances: amino acids or other organic acids, such as citric acid. The benefit of chelated zinc is that the organic substances help carry zinc through the intestinal wall and into your bloodstream.
