Ntishobora gushonga mu mazi, ikaba ishonga muri benzene na chloroform. Ishobora kuvangwa na methanol, ethanol, ether na tetrachloride ya karuboni. Kubera ko ifite double bond, ishobora gushonga mu mwuka, bityo igatanga impumuro mbi ikagira ibara ry'umuhondo. Iyo ikoresheje oxyde za azote, aside nitrique, nitrate ya mercurous na aside sulfure mu kuvura, ishobora guhindurwamo aside elaidike. Ishobora guhindurwamo aside stearic iyo ikoreshejwe hydrogenation. Double bond biroroshye kuyikoresha hamwe na halogen kugira ngo ikore aside halogen stearic. Ishobora kuboneka binyuze mu gushonga amavuta ya elayo n'amavuta y'ibinure, hagakurikiraho gushonga umwuka no gushushanya cyangwa gukuramo kugira ngo bitandukanywe. Aside oleic ni solvent nziza ku yandi mavuta, aside liqueur n'ibintu bishonga mu mavuta. Ishobora gukoreshwa mu gukora isabune, amavuta, ibintu bitera flotation, nk'amavuta na oleate.
Ikoreshwa:
GB 2760-96 isobanura ko ari uburyo bwo gutunganya. Ishobora gukoreshwa nk'ikintu kirwanya ifuro, impumuro nziza, ikintu gifunga, n'amavuta yo kwisiga.
Ishobora gukoreshwa mu gukora isabune, amavuta yo kwisiga, ibintu bitera guhindagurika kw'amazi, amavuta yo kwisiga na oleate, ikaba kandi ari umuti mwiza cyane wo gushonga aside irike n'ibintu bishonga mu mavuta.
Ishobora gukoreshwa mu gusiga neza zahabu, ifeza n'andi mabuye y'agaciro ndetse no gusiga neza mu nganda zikora ibikoresho by'amashanyarazi.
Ishobora gukoreshwa nk'ibisubizo byo gusesengura, ibishongesha, amavuta yo kwisiga n'ibikoresho byo gukwirakwiza isukari, ariko kandi ikoreshwa mu nganda zitunganya isukari.
Aside ya oleic ni umwimerere w’ibinyabutabire kandi ishobora gukora ester ya aside oleic ya epoxidized nyuma yo gukurwaho. Ishobora gukoreshwa nk'iplastike ya pulasitiki no gukora aside azelaic binyuze mu gukurwaho oxidation. Ni umwimerere w’ibuye rya polyamide. Byongeye kandi, aside oleic ishobora kandi gukoreshwa nk'inyunganiramirire y’imiti yica udukoko, ibikoresho byo gucapa no gusiga irangi, ibintu bishongesha mu nganda, ibikoresho byo gukurura amabuye y’agaciro mu byuma, n'ibikoresho byo kurekura. Byongeye kandi, ishobora gukoreshwa nk'ibikoresho fatizo mu gukora impapuro za karuboni, urushinge rw'uruziga no kwandika impapuro za wax. Ubwoko butandukanye bw'ibicuruzwa bya oleate nabyo ni ibintu by'ingenzi bikomoka kuri aside oleic. Nk'ikintu gikoreshwa mu buvuzi, ishobora gukoreshwa nk'icyitegererezo cyo kugereranya chromatographic no mu bushakashatsi ku binyabuzima, mu gupima kalisiyumu, umuringa na manyeziyumu, sulfur n'ibindi bintu.
Ishobora gukoreshwa mu bushakashatsi bwa biochemical. Ishobora gukora poroteyine kinase C mu turemangingo tw'umwijima.
Ibyiza:
Aside oleic ni aside irike iboneka mu mavuta y'inyamaswa n'ibimera. Aside oleic ni ibinure byuzuyemo amavuta menshi bikunze kwitwa ko ari byiza ku buzima bw'umuntu. Mu by'ukuri, ni aside irike ikomeye iboneka mu mavuta ya elayo, igizwe na 55 kugeza kuri 85 ku ijana by'ikintu cy'ingenzi, gikoreshwa cyane mu biryo byo mu nyanja ya Mediterane kandi cyarashimiwe imiterere yacyo kuva kera. Ubushakashatsi bwa none bushyigikira igitekerezo cy'inyungu zo kurya amavuta ya elayo, kuko ibimenyetso bigaragaza ko aside oleic ifasha kugabanya urugero rwa lipoproteine ​​nkeya (LDL) mu maraso, mu gihe bigatuma urugero rwa lipoproteine ​​nyinshi (HDL) rudahinduka. Iboneka kandi ku bwinshi mu mavuta ya canola, cod liver, kokonati, soya, na almond, aside oleic ishobora gukoreshwa mu masoko atandukanye, amwe muri yo ashobora kuba afite urugero rwinshi rwa aside irike y'agaciro bitewe n'imbaraga z'abahanga mu by'imiterere y'ibinyabuzima.
Aside ya oleic iboneka mu buryo busanzwe kurusha izindi aside irike zose. Iboneka nka glycerides mu binure byinshi n'amavuta. Ingano nini ya aside ya oleic ishobora kugabanya urugero rwa cholesterol mu maraso. Ikoreshwa mu nganda z'ibiribwa mu gukora amavuta na foromaje. Ikoreshwa kandi mu kuryoshya ibiryo bitetse, bombo, ice cream, na soda.
Nk’uko bivugwa n’Ishyirahamwe ry’Abanyamerika rishinzwe Diyabete, Abanyamerika barenga miliyoni 25 bafite diyabete. Byongeye kandi, miliyoni 7 bafite diyabete itaramenyekana, naho abandi miliyoni 79 bafite diyabete itaramenyekana. Mu bushakashatsi bwasohotse muri Gashyantare 2000 mu kinyamakuru cy’ubuvuzi "QJM," abashakashatsi bo muri Irilande basanze indyo ikungahaye kuri aside oleic yatumye isukari yo mu maraso y’abitabiriye itangira kwiyiriza ubusa, ubushobozi bwa insuline n’ingendo z’amaraso zitembera neza. Kugabanya isukari yo mu maraso n’umusemburo wa insuline, hamwe no kongera amaraso, bigaragaza ko diyabete igenzurwa neza kandi ko hakiri kare hashobora kugabanuka ibyago byo kurwara izindi ndwara. Ku bantu babarirwa muri za miriyoni barwaye diyabete n’umusemburo itaramenyekana, kurya ibiryo bikungahaye kuri aside oleic bishobora kuba ingirakamaro mu kugenzura iyi ndwara.
