Umenzi Ixabiso Elihle I-Oleic acid CAS:112-80-1

I-Oleic acid, i-Oleic acid, ekwaziwa ngokuba yi-cis-9-octadecenoic acid, eneempawu zeekhemikhali ze-single unsaturated carboxylic acid kwaye ifumaneka kakhulu kwiioyile zezilwanyana nezemifuno. Umzekelo, ioyile yomnquma iqulethe malunga ne-82.6%; ioyile yamandongomane iqulethe i-60.0%; ioyile yesesame iqulethe i-47.4%; ioyile yesoya iqulethe i-35.5%; ioyile yembewu yelanga iqulethe i-34.0%; ioyile ye-cottonseed iqulethe i-33.0%; ioyile yerapeseed iqulethe i-23.9%; ioyile yesafflower iqulethe i-18.7%; umxholo kwioyile yeti unokuba phezulu ukuya kwi-83%; kwioyile yezilwanyana: ioyile yelard iqulethe malunga ne-51.5%; ibhotolo iqulethe i-46.5%; ioyile yewhale iqulethe i-34.0%; ioyile yekhrimu iqulethe i-18.7%; i-Oleic acid ineentlobo ezimbini ezizinzileyo (uhlobo lwe-α) kunye nezingazinzile (uhlobo lwe-β). Kubushushu obuphantsi, inokuvela njengekristale; Xa kushushu kakhulu, ibonakala njengolwelo olunamafutha olungenambala nolucacileyo olunevumba le-lard. Inobunzima be-molecular obuyi-282.47, uxinano oluyi-0.8905 (20 ℃ ulwelo), i-Mp ye-16.3 ° C (α), i-13.4 ° C (β), iqondo lokubila le-286 ° C (13.3 103 Pa), i-225 ukuya kwi-226 ° C (1.33 103 Pa), i-203 ukuya kwi-205 ° C (0.677 103 Pa), kunye ne-170 ukuya kwi-175 ° C (0.267 103 ukuya kwi-0.400 103 Pa), i-Refractive index ye-1.4582 kunye ne-viscosity ye-25.6 mPa • s (30 ° C).
Ayinyibiliki emanzini, iyanyibilika kwi-benzene kunye ne-chloroform. Ixutywa ne-methanol, i-ethanol, i-ether kunye ne-carbon tetrachloride. Ngenxa yokuba ine-double bond, inokuthi ichaphazeleke lula yi-air oxidation, ngaloo ndlela ivelise ivumba elibi kunye nombala ojika ube mthubi. Xa kusetyenziswa i-nitrogen oxides, i-nitric acid, i-mercurous nitrate kunye ne-sulfurous acid ukunyanga, inokuguqulwa ibe yi-elaidic acid. Ingaguqulwa ibe yi-stearic acid xa i-hydrogenation ingena kwi-hydrogenation. I-double bond kulula ukuyiphendula ne-halogen ukuvelisa i-halogen stearic acid. Ingafunyanwa ngokutsalwa kwe-hydrolysis ye-olive oil kunye ne-lard oil, kulandele ukunyibilikiswa ngomphunga kunye ne-crystallization okanye ukutsalwa ukuze kwahlulwe. I-oleic acid sisinyibilikisi esibalaseleyo kwezinye iioyile, ii-fatty acids kunye nezinto ezinyibilikayo kwioyile. Ingasetyenziselwa ukwenza isepha, izinto zokuthambisa, ii-flotation agents, ezifana ne-ointment kunye ne-oleate.

Ingasetyenziswa njengee-reagents zohlalutyo, izinyibilikisi, izinto zokuthambisa kunye ne-arhente yokudada, kodwa ikwasetyenziswa nakwishishini lokucubungula iswekile.
I-Oleic acid sisixhobo esiluhlaza sekhemikhali esiphilayo kwaye sinokuvelisa i-epoxidized oleic acid ester emva kwe-epoxidation. Ingasetyenziswa njengeplastiki yeplastiki kunye nokuvelisa i-azelaic acid nge-oxidation. Yinto eluhlaza eyenziwe yi-polyamide resin. Ukongeza, i-oleic acid ingasetyenziswa njenge-pesticide emulsifier, i-printing and dyeing auxiliaries, i-industrial solvents, i-metal mineral flotation agent, kunye ne-release agent. Ngaphezu koko, ingasetyenziswa njengesixhobo esiluhlaza sokwenza iphepha lekhabhoni, i-round bead kunye nephepha le-wax lokubhala. Iintlobo ngeentlobo zeemveliso ze-oleate nazo zizinto ezibalulekileyo eziphuma kwi-oleic acid. Njenge-chemical reagent, ingasetyenziswa njengesampulu yokuthelekisa i-chromatographic kunye nophando lwe-biochemical, ukufumanisa i-calcium, i-copper kunye ne-magnesium, i-sulfur kunye nezinye izinto.
Ingasetyenziswa kwizifundo ze-biochemical. Ingavuselela i-protein kinase C kwiiseli zesibindi.
Iingenelo:
I-Oleic acid yi-fatty acid efumaneka kwiioyile zezilwanyana nemifuno. I-Oleic acid yi-mono-saturated fatty ekholelwa ukuba ilungile kwimpilo yomntu. Enyanisweni, yi-fatty acid ephambili efumaneka kwioyile yomnquma, equka ama-55 ukuya kuma-85 ekhulwini ento ebalulekileyo, esetyenziswa kakhulu ekutyeni kweMeditera kwaye ibisoloko idunyiswa ngenxa yeempawu zayo zonyango ukususela kudala. Izifundo zanamhlanje zixhasa ingcamango yeenzuzo zokutya ioyile yomnquma, kuba ubungqina bubonisa ukuba i-oleic acid inceda ukwehlisa amanqanaba e-low-density lipoproteins (LDLs) eziyingozi egazini, ngelixa ishiya amanqanaba e-high-density lipoproteins (HDLs) eziluncedo zingatshintshi. Ikwafumaneka ngobuninzi obukhulu kwi-canola, isibindi se-cod, ikhokhonathi, i-soybean, kunye neoyile ze-almond, i-oleic acid inokutyiwa kwimithombo eyahlukeneyo, eminye yayo enokuba kungekudala iqulethe amanqanaba aphezulu e-fatty acid exabisekileyo ngenxa yemizamo yeenjineli zezakhi zofuzo.
I-oleic acid ivela ngokwendalo ngobuninzi obukhulu kunayo nayiphi na enye i-fatty acid. Ifumaneka njenge-glycerides kumafutha amaninzi kunye neeoyile. Ubuninzi be-oleic acid bunokunciphisa amanqanaba e-cholesterol egazini. Isetyenziswa kwishishini lokutya ukwenza iibhotolo zokwenziwa kunye neetshizi. Ikwasetyenziselwa ukunambitha izinto ezibhakiweyo, iilekese, i-ayisikhrim kunye neesoda.
Ngokutsho kwe-American Diabetes Association, abantu baseMelika abangaphezu kwezigidi ezingama-25 banesifo seswekile. Ukongeza, izigidi ezisi-7 banesifo seswekile esingafunyaniswanga, kwaye abanye abazizigidi ezingama-79 banesifo seswekile. Kwisifundo esapapashwa ngoFebruwari 2000 kwijenali yezonyango ethi "QJM," abaphandi baseIreland bafumanise ukuba ukutya okutyebileyo kwi-oleic acid kuphucula i-glucose ye-plasma yokuzila ukutya yabathathi-nxaxheba, ukuva i-insulin kunye nokujikeleza kwegazi. Amanqanaba e-glucose yokuzila ukutya aphantsi kunye ne-insulin, kunye nokuhamba kwegazi okuphuculweyo, kubonisa ulawulo olungcono lweswekile kunye nomngcipheko omncinci wezinye izifo. Kwizigidi zabantu abanesifo seswekile kunye nesifo seswekile esingaphambi kwexesha, ukutya ukutya okutyebileyo kwi-oleic acid kunokuba luncedo ekulawuleni esi sifo.
