Abstract

Feromoni su složeni organski spojevi koji su odgovorni za komunikaciju između pripadnika iste vrste. U početku su bili definirani kao kemijski spojevi koji su odgovorni samo za spolno privlačenje insekata, međutim danas su poznate još mnoge druge uloge kao što su agregacija (združivanje), društvena hijerarhija, upozoravanje na opasnost, obilježavanje puta do hrane i dr. Karakteristični su za cijeli živi svijet, a budući da imaju široko područje djelovanja karakterizira ih i velika strukturna raznolikost – od malih hlapljivih molekula do velikih proteinskih kompleksa. Omjer komponenata feromonske smjese izravno je vezan uz učinak feromona. Izoliraju se iz organizama ili kemijski sintetiziraju, a unatoč velikoj strukturnoj raznolikosti, da bi komunikacija između vrsta bila uspješna nužno je da signal u obliku feromona bude odgovarajuće strukture, konformacije i kiralnosti. Njihova detekcija i karakterizacija se vrši pomoću raznih spektroskopskih metoda poput ultraljubičaste (UV) i infracrvene (IR) spektroskopije te spektroskopije nuklearne magnetske rezonancije (NMR), kao i najčešće korištene spregnute tehnike plinska kromatografija-spektrometrija masa (GC MS).

Abstract (english)

Pheromones are complex organic compounds that are responsible for communication between members of the same species. Originally, they were defined as chemical compounds responsible only for the sexual attraction of insects, but today many other functions are known, such as aggregation, social hierarchy, warning of danger, marking the way to food, etc. They are characteristic of the entire living world, and since they have a broad field of activity, they are characterized by a great structural diversity - from small volatile molecules to large protein complexes. The ratio of the components of the pheromone mixture is directly related to the effect of the pheromone. They are isolated from organisms or chemically synthesized, and despite the great structural diversity, it is necessary for successful com munication between species that the signal in the form of pheromones has the appropriate structure, conformation and chirality. Their detection and characterization is carried out using various spectroscopic methods such as ultraviolet (UV) and infrared (IR) spectroscopy, nuclear magnetic resonance (NMR) and the most commonly used mass spectroscopy in combination with gas chromatography (GC-MS).
