Chemistry Several drugs, foods and other products have a particular structure in their molecules, which is essential for the biological effect (therapeutic), or their molecules exhibit isomerism. After all what is isomerism? What does that word mean? You live with it daily and do not know! The chemical formula H O is recognized worldwide as the chemical formula of water and no other substance that has this same formula. However, the same does not happen with the molecular formulas of organic compounds. A query the catalogs as "Chemical Abstracts" shows that there are hundreds of different organic compounds with the same molecular formula. For example, the molecular formula C is the formula of ethyl alcohol or "common alcohol" and also the formula for the methyl ether. The first to observe this important feature was the chemist Jöns Jacob Berzelius when his disciple, the German chemist Friedrich Wöhler produced urea CO (NH (organic compound) by ammonium cyanate NH OCN (inorganic). Both have the same molecular formula (C Berzelius proposed an explanation to the phenomenon: "call the substances of the same composition but different properties of isomers" (Greek iso = same and mere = part), meaning "equal". Better understand the phenomenon, analyzing analogy: how many different words you can write combining various forms of the letters A, O, C and S. There are several combinations, such as CASE, BAG, OCAS, etc.. the same happens with the organic compounds. There are different compounds having the same molecular formula.

Kemija Nekoliko lijekovi, hrana i drugi proizvodi imaju određenu strukturu u svojim molekulama, što je bitno za biološki učinak (terapijska), ili njihove molekule izložbeni isomerism. Nakon svega što je isomerism? Što znači ta riječ? Možete živjeti s njom svaki dan, a ne znam! Kemijska formula H O je priznat u svijetu kao kemijsku formulu vode i bez druge tvari koja ima ovu istu formulu. Međutim, isto se ne događa sa molekularnih formula organskih spojeva. Upit su katalozi kao "Kemijski sažetaka" pokazuje da postoje stotine različitih organskih spojeva s iste molekularne formule. Na primjer, molekularna formula C je formula etilnog alkohola ili "uobičajena alkohol" i formula za metil eter. Prvi promatrati ovu važnu značajku bio kemičar Jöns Jacob Berzelius kada je njegov učenik, njemački kemičar Friedrich Wöhler proizvedene uree CO (NH (organske spojeve) koje amonijevog cijanata NH OCN (anorganske). Oboje imaju istu molekularnu formulu (C Berzelius predložio objašnjenje fenomena: "pozvati tvari istog sastava, ali različite svojstva izomera" (grčki = iso isto i sama = dio), što znači "jednaki". Bolje razumijevanje fenomena, analizu analogiju: koliko različitih riječi možete pisati kombinirajući razne oblike slova A, O, C i S. Postoji nekoliko kombinacija, kao što je slučaj, torba, OCAS, itd.. Isto se događa i sa organskim spojevima. Postoje različiti spojevi koji imaju istu molekularnu formulu.
