Basa remafuta acids mumuviri womunhu.
Chii chinonzi fatty acids? Iyi ndiyo carboxylic acid kubva mukuumbwa kwemafuta nemafuta emhuka. Vanoita simba rekushanda, nokuti nekuparara kweAicid mu mumuviri, simba rinoumbwa, pamwe nebasa replastiki, nokuti acids inobatanidzwa mukugadzirwa kwemumakumbo, iyo inoita skeleton yemiti uye mhuka dzemhuka. Zvechokwadi mafuta ose acids akaparadzaniswa kuva unsaturated uye akazara. Zvimwe zvinobatsira pasaturated mafuta acids, nokuti vanogadzira zvinhu zvinoshandiswa zvehupenyu zve prostaglandin uye vanoita basa rakananga mumatabolism.
Fatty acids inogadzirwa muropa, mumadziro emukumbo, mu pulmonary uye mafuta mashupu, mumapfupa emapfupa uye mamwe matukisi. Fatty acids zvakare chikamu chemaridhi zvakasiyana-siyana: phosphatides, glycerides, waxes, cholesterol, nezvimwe zvinhu zvinotora chikamu chinoshanda mumatabolism.
Chii chinonzi oleic acid? Basa reAicids mumuviri womunhu.
Iooic acid ndiyo yakareba mafuta isaturated mono-asidi, iyo iri chikamu chemafuta (lipids) anobatanidzwa mukugadzirwa kwemakumbo, uye kutsanangura dzimba dzemap lipid zvakanyanya. Nzira yekushandura oleic acids mu lipids inowanikwa muzvinyorwa zvehupenyu nemamwe mafuta acids anonyanya kushandura chinongororwa chehupenyu hwe membrane, inonzi kupora. Kuvapo kwemazana akawanda emafuta akafanana mumafuta emafuta evanhu anochengetedza kunodzivirira kwe lipids kubva kune zvakasvibiswa nezana shoma re antioxidants.
Oleic acid, inowanikwa, inotora mafuta anogadziriswa anokwanisa kushandiswa, somuenzaniso, mumasero muropa rechiropa. Asi oleic acids, pamwe nezvose izvi, ndeimwe yezvinyanya kuwanikwa acid inowanikwa mumafuta ezvokudya. Oleic acid inobatsira zvikuru mukudya kwevanhu. Mafuta, umo zvinyorwa zve oleic acid zvinowedzera, zvakanyanya kudyiwa. Mukurapa, kunyange kugadzirirwa kwemishonga kunoshandiswa, mune hwaro iyo oleic acid ine linetol.
Mumakambani, oleic acid inoshandiswa sechikonzero chekugadzirwa kwekupfeka, varnishes, kuomesera mafuta, eamels, peint. Inoshandiswawo sePlastiki zvinhu muzvinonhuwira, uye marashi ayo - mu detergents.
Iyi asidi inopa simba kumuviri, seimwe mafuta akawanda acids. Simba rinosunungurwa nehujijidhi ye oleic mafuta acids mushure mekuparadzanisa kwavo kubva mumapukisa ari pasi pezvinoitwa pancreatic juisi. Iyo yakatangira aya aya acids inokonzerwa ne-enzyme chaiyo inonzi oxygenase, iyo inowanikwa mumafuta masukisi uye chiropa.
Oleic acids inowanikwa kubva mumafuta omuorivhi panguva dzakawanda kristalllization mushure mekuparadzwa kwe lipids. Kutsigira kwehuwandu uye hwehutano hwe oleic acid inogadzirwa ne gas-liquid chromatography.
Kukosha kwe oleic acid muhutano hwevanhu.
Mumafuta ezvipfuwo, oleic acid inokwana 40% yehutano hwezvose acid, uye inenge iri mumafuta ose emafuta - anenge 30%. Kunyanya kuine maoicic acid, mafuta omuorivhi uye mafuta epepanut.
Oleic acid inoshandurana, pasinei nokuti mune kudya kwevanhu kunofungidzirwa kuti ndiyo inofadza zvikuru, iyo iri pedyo zvikuru nezvose zvinowanikwa mumafuta evanhu. Izvi ndizvo zvinodzivirira chido chekuvaka patsva mafuta ekunyorwa kwema lipids anouya nekudya, izvo zvinoreva kuti hapazovi nekushaiwa zvisina kufanira kwezvinhu uye simba mumuviri womunhu.
Iyo yakakosha yekudya ye oleic mafuta acids nechikafu inopiwa nekucherechedza mazano ekudya kwakakwana, maererano nezvinodiwa pakudya kwevanhu zviviri zvezvitatu zvemafuta zvinofanira kuva mhuka, uye chetatu chemidziyo yakabva. Muchiitiko ichi, kudya kunenge kune 40% oleic acid. Mushure mekunge kupisa kwemafuta ane pfuma ye oleic acids, ivo vashoma kuparadzwa nehujijidhe kupfuura mamwe mafuta. Ichi ndicho chikonzero chekushandiswa kwemafuta mukutsva kweimwe michina kubva muzviyo, mbatata, nezvimwewo, pamwe nekudurura zvokudya zvekudya.
Mushure mokunge hydrogenation yemafuta yemafuta, trans-oleic acids inoumbwa kuti ibudise zvigadzirwa zvemafuta zvemargarines. Ichi chinotyisa, seyleic acids, chinonyatsopindirwa nemuviri womunhu, asi zvishoma nezvishoma mumafuta aripo.
Oleic acids inokosha pakugadzirisa metabolism yakakodzera.
