Chemical element chemical bonds, they form chemical compounds. Only a minority of elements are found uncombined as relatively pure minerals. Among the more common of such native elements are copper, silver, gold, carbon (as coal, graphite, or diamonds), and sulfur. All but a few of the most inert elements, such as noble gases and noble metals, are usually found on Earth in chemically combined form, as chemical compounds. While about 32 of the chemical elements occur on Earth in native uncombined forms, most of these occur as mixtures. For example, atmospheric air is primarily a mixture of nitrogen, oxygen, and argon, and
CU-2010 and CU-2020 of free radicals and less lipid peroxidation with the amount of malonaldehyde in the heart tissue being reduced. However, the activation of neutrophils does not seem to be altered. CU-2010 and CU-2020 improve coronary endothelial function similarly to aprotinin. Unlike aprotinin, at high doses, their anti-inflammatory properties allow for the improvement in the recovery of contractility in the left ventricle after ischemic conditions, and increase the protection of the myocardium. Moreover, CU-2010 and CU-2020 do not compromise clot strength, and do not affect the function of vascular smooth muscle. CU-2010 and CU-2020 CU-2010 and CU-2020 are synthetic compounds that act
