Hainyungudike mumvura, inonyungudika mu benzene ne chloroform. Inosanganiswa ne methanol, ethanol, ether uye carbon tetrachloride. Nekuda kwekuva ne double bond, inogona kuomeswa nemhepo, zvichiita kuti iite hwema hwakaipa neruvara rwunoshanduka kuita yero. Kana ikashandisa nitrogen oxides, nitric acid, mercurous nitrate uye sulphurous acid pakurapa, inogona kushandurwa kuita elaidic acid. Inogona kushandurwa kuita stearic acid kana yaiswa hydrogenation. Double bond iri nyore kuita ne halogen kuti igadzire halogen stearic acid. Inogona kuwanikwa kuburikidza ne hydrolysis yemafuta emuorivhi nemafuta emafuta emafuta, ichiteverwa ne steam distillation uye crystallization kana kubviswa kuti iparadzaniswe. Oleic acid i solvent yakanaka kune mamwe mafuta, fatty acids nezvinhu zvinonyungudika mumafuta. Inogona kushandiswa kugadzira sipo, mafuta, zvinhu zvinosanganisa flotation, zvakaita se oil ne oleate.
Mashandisirwo:
GB 2760-96 inotsanangura semubatsiri wekugadzirisa. Inogona kushandiswa semushonga wekudzivirira furo, hwema, chinobatanidza, uye semafuta.
Inogona kushandiswa kugadzira sipo, mafuta ekuzora, zvinhu zvinoyamura, mafuta ekuzora uye oleate, ichivawo chinhu chinonyungudutsa mafuta akawanda nezvinhu zvinonyungudika mumafuta.
Inogona kushandiswa pakukwesha goridhe, sirivha nedzimwe simbi dzinokosha nemazvo pamwe nekukwesha muindasitiri yekugadzira mapurasitiki.
Inogona kushandiswa sezvinhu zvinoongorora, zvinonyungudutsa, mafuta ekufambisa uye chinhu chinobatsira pakuyerera kwemvura, asiwo inoshandiswa muindasitiri yekugadzira shuga.
Oleic acid imhando yemakemikari inogadzirwa nemakemikari uye inogona kugadzira epoxidized oleic acid ester mushure mekusanganiswa. Inogona kushandiswa sepurasitiki inogadzirisa uye kugadzira azelaic acid kuburikidza nekusanganiswa. Ndiyo mhando ye polyamide resin. Pamusoro pezvo, oleic acid inogona kushandiswawo semulsifier wezvipembenene, kudhinda nekudhaya, zvinonyungudutsa mumaindasitiri, metal mineral flotation agent, uye release agent. Uyezve, inogona kushandiswa semhando yekugadzirwa kwekabhoni paper, round bead uye typing wax paper. Mhando dzakasiyana dzezvigadzirwa zve oleate zvakare zvinhu zvakakosha zvinobva ku oleic acid. Semakemikari anoshandiswa, inogona kushandiswa se chromatographic comparison sample uye yekutsvagisa biochemical, kuona calcium, copper ne magnesium, sarufa nezvimwe zvinhu.
Inogona kushandiswa muzvidzidzo zvebiochemical. Inogona kumutsa protein kinase C mumasero echiropa.
Mabhenefiti:
Oleic acid iasidhi ine mafuta inowanikwa mumafuta emhuka nemiriwo. Oleic acid iasidhi ine mafuta akawanda anowanzo fungidzirwa kuti akanaka pahutano hwemunhu. Zvechokwadi, ndiyo asidi ine mafuta akawanda inowanikwa mumafuta emuorivhi, ine 55 kusvika 85 muzana yezvinhu zvakakosha, iyo inowanzoshandiswa mukubika kweMediterranean uye yave ichirumbidzwa nekuda kwehunhu hwayo hwekurapa kubvira kare. Zvidzidzo zvemazuva ano zvinotsigira pfungwa yekubatsira kwekudya mafuta emuorivhi, sezvo humbowo hunoratidza kuti oleic acid inobatsira kuderedza huwandu hwema low-density lipoproteins (LDLs) anokuvadza muropa, ukuwo ichisiya huwandu hwema high-density lipoproteins (HDLs) husina kuchinja. Inowanikwawo muhuwandu hwakawanda mumafuta e canola, cod liver, coconut, soybean, uye almond, oleic acid inogona kudyiwa kubva kwakasiyana-siyana, mamwe acho anogona kunge aine huwandu hwakawanda hwemafuta acid nekuda kwekuedza kwemajini mainjiniya.
Oleic acid inowanikwa zvakasikwa yakawanda kupfuura chero imwe fatty acid. Inowanikwa se glycerides mumafuta mazhinji nemafuta. Kuwanda kwe oleic acid kunogona kuderedza cholesterol muropa. Inoshandiswa muindasitiri yezvikafu kugadzira mafuta ekugadzira uye chizi. Inoshandiswawo kunakisa zvinhu zvakabikwa, masiwiti, ice cream, uye sodas.
Sekureva kweAmerican Diabetes Association, vanhu vanopfuura mamiriyoni makumi maviri nemashanu vekuAmerica vane chirwere cheshuga. Pamusoro pezvo, mamiriyoni manomwe vane chirwere cheshuga chisati chaonekwa, uye mamiriyoni makumi manomwe nemapfumbamwe vane prediabetes. Muongororo yakaburitswa muna Kukadzi 2000 mumagazini yezvekurapa "QJM," vaongorori vekuIreland vakaona kuti kudya kwakapfuma mu oleic acid kwakavandudza shuga yeropa yevanotora chikamu mufasting plasma, insulin sensitivity uye kutenderera kweropa. Kudzikira kwemazinga eglucose yekutsanya ne insulin, pamwe nekuwedzera kuyerera kweropa, zvinoratidza kudzora chirwere cheshuga zviri nani uye njodzi shoma yezvirwere. Kune mamiriyoni evanhu vane chirwere cheshuga ne prediabetes, kudya chikafu chakapfuma mu oleic acid kunogona kubatsira mukutonga chirwere ichi.
