Umkhiqizi Intengo Enhle I-Oleic acid CAS:112-80-1

I-Oleic acid, i-Oleic acid, eyaziwa nangokuthi i-cis-9-octadecenoic acid, enezakhiwo zamakhemikhali ze-single unsaturated carboxylic acid futhi ivezwa kabanzi emafutheni ezilwane nemifino. Isibonelo, uwoyela womnqumo uqukethe cishe u-82.6%; uwoyela wamakinati uqukethe u-60.0%; uwoyela wesesame uqukethe u-47.4%; uwoyela wesoya uqukethe u-35.5%; uwoyela wembewu yelanga uqukethe u-34.0%; uwoyela we-cottonseed uqukethe u-33.0%; uwoyela we-rapeseed uqukethe u-23.9%; uwoyela we-safflower uqukethe u-18.7%; okuqukethwe uwoyela wetiye kungaba phezulu ku-83%; emafutheni ezilwane: uwoyela we-lard uqukethe cishe u-51.5%; ibhotela liqukethe u-46.5%; uwoyela womkhomo uqukethe u-34.0%; uwoyela wokhilimu uqukethe u-18.7%; i-Oleic acid inezinhlobo ezimbili ezizinzile (uhlobo lwe-α) kanye nezinhlobo ezingazinzile (uhlobo lwe-β). Uma izinga lokushisa liphansi, lingabonakala njengekristalu; Uma izinga lokushisa liphezulu, libonakala njengoketshezi olunamafutha olungenambala olubonakalayo olunephunga lamafutha. Linobunzima bama-molecule obungu-282.47, ubuningi obungu-0.8905 (20 ℃ uketshezi), i-Mp engu-16.3 ° C (α), 13.4 ° C (β), iphuzu lokubila elingu-286 °C (13.3 103 Pa), 225 kuya ku-226 °C (1.33 103 Pa), 203 kuya ku-205 °C (0.677 103 Pa), kanye no-170 kuya ku-175 °C (0.267 103 kuya ku-0.400 103 Pa), inkomba ye-Refractive engu-1.4582 kanye ne-viscosity engu-25.6 mPa • s (30 ° C).
Ayincibiliki emanzini, iyancibilika ku-benzene kanye ne-chloroform. Ixubene ne-methanol, i-ethanol, i-ether kanye ne-carbon tetrachloride. Ngenxa yokuthi iqukethe i-double bond, ingaba ngaphansi kwe-oxidation yomoya kalula, ngaleyo ndlela ikhiqize iphunga elibi nombala ophenduka ophuzi. Uma kusetshenziswa ama-nitrogen oxides, i-nitric acid, i-mercurous nitrate kanye ne-sulfurous acid ukuze kwelashwe, ingaguqulwa ibe yi-elaidic acid. Ingaguqulwa ibe yi-stearic acid uma i-hydrogenation ingena. I-Double bond kulula ukusabela ne-halogen ukuze kukhiqizwe i-halogen stearic acid. Ingatholakala ngokufaka i-hydrolysis yamafutha omnqumo namafutha e-lard, kulandelwe yi-steam distillation kanye ne-crystallization noma ukukhipha ukuze kuhlukaniswe. I-oleic acid iyisisombululo esihle kakhulu kwamanye amafutha, ama-fatty acid kanye nezinto ezincibilika kumafutha. Ingasetshenziswa ekwenzeni insipho, izinto zokugcoba, izinto zokuthambisa, njenge-ointment kanye ne-oleate.
Ukusetshenziswa:
I-GB 2760-96 iyichaza njengosizo lokucubungula. Ingasetshenziswa njenge-antifoaming agent, iphunga elimnandi, i-binder, kanye ne-lubricant.
Ingasetshenziswa ekwenzeni insipho, izinto zokugcoba, izinto zokuthambisa, amafutha kanye ne-oleate, futhi iyisisombululo esihle kakhulu sama-fatty acid nezinto ezincibilika ku-oyela.
Ingasetshenziswa ekupholisheni igolide, isiliva nezinye izinsimbi eziyigugu ngokunembile kanye nasekupholisheni embonini ye-electroplating.
Ingasetshenziswa njengezinto zokuhlaziya, izinyibilikisi, izinto zokugcoba kanye ne-ejenti yokuntanta, kodwa futhi ingasetshenziswa embonini yokucubungula ushukela.
I-Oleic acid iyinto eluhlaza yamakhemikhali ephilayo futhi ingakhiqiza i-ester ye-oleic acid ehlanganisiwe ngemva kokuhlanganiswa. Ingasetshenziswa njenge-plasticizer yepulasitiki kanye nokukhiqizwa kwe-azelaic acid nge-oxidation. Iyinto eluhlaza ye-polyamide resin. Ngaphezu kwalokho, i-oleic acid ingasetshenziswa futhi njenge-pesticide emulsifier, izinsiza zokunyathelisa nokudaya, izinyibilikisi zezimboni, i-ejenti yokuntanta kwamaminerali ensimbi, kanye ne-ejenti yokukhulula. Ngaphezu kwalokho, ingasetshenziswa njengezinto zokusetshenziswa zokukhiqiza iphepha lekhabhoni, ubhontshisi obuyindilinga kanye nephepha le-wax lokuthayipha. Izinhlobo ezahlukene zemikhiqizo ye-oleate nazo ziyizinto ezibalulekile ezithathwe ku-oleic acid. Njenge-reagent yamakhemikhali, ingasetshenziswa njengesampula yokuqhathanisa i-chromatographic kanye nocwaningo lwe-biochemical, ukuthola i-calcium, ithusi kanye ne-magnesium, i-sulfur nezinye izinto.
Ingasetshenziswa ezifundweni ze-biochemical. Ingavuselela i-protein kinase C emaseli esibindi.
Izinzuzo:
I-Oleic acid iyi-fatty acid etholakala emafutheni ezilwane nemifino. I-Oleic acid iyi-mono-saturated fatty ngokuvamile ekholelwa ukuthi ilungele impilo yomuntu. Ngempela, iyi-fatty acid eyinhloko etholakala emafutheni omnqumo, equkethe amaphesenti angu-55 kuya kwangu-85 ento ebalulekile, evame ukusetshenziswa ekudleni kwaseMedithera futhi ibilokhu idunyiswa ngezici zayo zokwelapha kusukela endulo. Izifundo zanamuhla zisekela umbono wezinzuzo zokudla uwoyela womnqumo, njengoba ubufakazi busikisela ukuthi i-oleic acid isiza amazinga ephansi ama-lipoprotein aphansi (ama-LDL) ayingozi egazini, kuyilapho ishiya amazinga ama-lipoprotein aphezulu (ama-HDL) anenzuzo engashintshi. Itholakala futhi ngobuningi obukhulu kuma-canola, isibindi se-cod, ukhukhunathi, isoya, kanye namafutha e-alimondi, i-oleic acid ingadliwa emithonjeni eyahlukahlukene, eminye yayo engase ibe namazinga aphezulu kakhulu e-fatty acid ebalulekile ngenxa yemizamo yonjiniyela bezakhi zofuzo.
I-oleic acid ivela ngokwemvelo ngobuningi obukhulu kunanoma iyiphi enye i-fatty acid. Ikhona njenge-glycerides emafutheni amaningi nasemafutheni. Amazinga aphezulu e-oleic acid anganciphisa amazinga e-cholesterol egazini. Isetshenziswa embonini yokudla ukwenza amabhotela noshizi okwenziwa. Iphinde isetshenziswe ekunambithekeni kwezimpahla ezibhakiwe, amaswidi, i-ayisikhilimu, nama-soda.
Ngokusho kwe-American Diabetes Association, abantu baseMelika abangaphezu kwezigidi ezingu-25 banesifo sikashukela. Ngaphezu kwalokho, izigidi ezingu-7 zinesifo sikashukela esingakahlolwa, kanti ezinye izigidi ezingu-79 zinesifo sikashukela sangaphambi kwesikhathi. Ocwaningweni olwanyatheliswa ngoFebhuwari 2000 kumagazini wezokwelapha i-"QJM," abacwaningi e-Ireland bathole ukuthi ukudla okucebile nge-oleic acid kuthuthukisa ushukela wegazi osheshayo wabahlanganyeli, ukuzwela kwe-insulin kanye nokujikeleza kwegazi. Ukwehla kwamazinga e-glucose yokuzila kanye ne-insulin, kanye nokugeleza kwegazi okuthuthukisiwe, kusikisela ukulawulwa okungcono kwesifo sikashukela kanye nengozi encane yezinye izifo. Ezigidini zabantu abanesifo sikashukela esitholakale benesifo sikashukela sangaphambi kwesikhathi, ukudla ukudla okucebile nge-oleic acid kungaba usizo ekulawuleni lesi sifo.
