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.

Magnesium amino acid chelate is usually bonded to a variety of amino acids, which are all larger molecules. In this form there is less magnesium by weight but the individual amino acids could all be beneficial for different things.agnesium Citrate. This is one of the most common forms of Mg on the commercial market. This is Mg bonded to citric acid, which increases the rate of absorption. Citrate is a larger molecule than the simple oxygen of oxide, so there is less magnesium by weight than in the oxide form.
