• The fact that they can be joined to form water, a substance used for putting out most kinds of fires, illustrates the types of changes elements undergo when they join to form compounds. (encyclopedia.com)
  • Numerous quaternary compounds (with four elements) of nickel have been studied for super conductivity properties, as nickel is adjacent to copper and iron in the periodic table can can form compounds with the same structure as the high-temperature superconductors that are known. (wikipedia.org)
  • In addition, we examined collective time course data for six individual protease targets, including average molecular weight of the compounds. (drugpatentwatch.com)
  • Organosulfur compounds can be classified according to the sulfur-containing functional groups , which are listed (approximately) in decreasing order of their occurrence. (wikipedia.org)
  • Each volume systematically covers occurrence of the compounds in plants, illustrations of chemical structures plus physical-chemical, spectral, and pharmacological data. (springer.com)
  • The entries are preceded by tabulated information on the occurrence of the compounds in plants etc. (springer.com)
  • The number of proteins mapped to compounds on a yearly basis shows less decline, indicating the cumulative published target capacity of global research is being sustained in the region of 300 proteins for large companies. (drugpatentwatch.com)
  • Fossil fuels, coal , petroleum , and natural gas , which are derived from ancient organisms, necessarily contain organosulfur compounds, the removal of which is a major focus of oil refineries . (wikipedia.org)
  • The azides, like the halogen compounds, readily react with other substances by displacement of the so-called azide group and yield many kinds of compounds. (britannica.com)
  • A compound is not the same as a mixture, which has a variable composition, but until chemists understood the atomic and molecular substructure of compounds, the distinction was not always clear. (encyclopedia.com)
  • Likewise, it is important to know just how to name a compound, using a uniform terminology, since there are far too many substances in the world to give each an individual name. (encyclopedia.com)
  • Elements make up compounds, and although there are only about 90 elements that occur in nature, there are literally many millions of compounds. (encyclopedia.com)
  • Likewise, a chemical change is required to break down a compound into its constituent elements. (encyclopedia.com)
  • The nature of a compound is almost paradoxical: the constituent elements remain the same, yet the compound typically bears little resemblance to the elements that form it. (encyclopedia.com)
  • ways of observing, writing names of ionic compounds from formulas and vice-versa (Note: It is not necessary that students be familiar with writing reactions and predicting products, as the ions that will react in each case are designated for them, and they only need to combine these ions. (uen.org)
  • We have used this database to analyse published compounds cumulatively linked to nearly 4000 protein target identifiers from multiple species over the last 20 years. (drugpatentwatch.com)
  • None of these is sweet, yet when they are brought together in just the right way, they make the compound that sweetens everything from breakfast cereals to colas. (encyclopedia.com)
  • A collection of visually stimulating and informative infographics about everyday compounds, which would make a valuable addition to any science classroom. (rsc.org)

  • A more open and specific count of historically advanced drug candidates can be obtained by performing a query in PubChem Compound for INN or USAN. (drugpatentwatch.com)
  • Students will practice making and recording observations about various compounds and their aqueous solutions, write the formulas for the compounds, then perform chemical reactions and write the names and formulas of the products. (uen.org)
  • You can't entirely eliminate these compounds from your daily life, but you can minimize the amount. (diynetwork.com)
