The organic nitrates, including nitroglycerin, isosorbide dinitrate and isosorbide mononitrate, act as prodrugs for nitric oxide (NO) which is a potent vasodilator gas. Nitric oxide activates guanylyl-cyclase in vascular endothelial cells, which increases intracellular cyclic GMP and thereby reduces intracellular calcium concentrates and dephosphorylates myosin light chains causing relaxation of smooth muscle cells.
Ammonium nitrate-sulfate (30-0-0 + 6.5S) is a dry nitrogen fertilizer relatively new to the United States. It is manufactured by reacting anhydrous ammonia with a mixture of nitric acid and sulfuric acid. The nitrogen content of the product will vary depending on the proportion of nitric to sulfuric acid.he reacted material is concentrated, prilled and coated to prevent caking. In ammonium nitrate, one-half of the nitrogen is in the nitrate form, and the other half is in the ammonium form. Ammonium nitrate is the preferred form of nitrogen fertilizer when it is to be applied on the soil surface and not incorporated.
