Indima yamafutha acids emzimbeni womuntu.
Ziyini ama-fatty acids? Lona i-acid carboxylic ekubunjweni kwamafutha nemifino. Benza umsebenzi wamandla, ngoba ngokuqhekeka kwama-acids emzimbeni, amandla akhiwa, kanye nomsebenzi wepulasitiki, ngoba ama-acids ahlanganyela ekwakhiweni kwezinambuzane, okwenza i-skeleton yamaseli ezitshalo nezilwane. Ngokuqinisekile wonke ama-acid acids ahlukaniswe abe unsaturated futhi agcwele. Ama-acid amaningi angasetshenzisiwe angasetshenzisiwe, ngoba akhiqiza izinto eziphilayo ezisebenzayo ze-prostaglandins futhi adlala indima eqondile ekusebenzeni kwe-metabolism.
Ama-acids amafutha ahlanganiswa esibindi, ezindongeni zamathumbu, emathisini we-pulmonary and fatty, emnothweni wethambo nezinye izicubu. Amafutha acatty nawo ayingxenye ye lipids ehlukahlukene kunazo zonke: i-phosphatides, i-glycerides, ama-wax, i-cholesterol, nezinye izakhi ezithatha isinyathelo esiwusizo ekusetshenzisweni kwemithi.
Yini ebizwa nge-oleic acid? Indima yama-acids emzimbeni womuntu.
I-oleic acid iyona ephezulu kakhulu yamafutha ayi-insulated mono-acid, engxenyeni yamafutha (lipids) abamba iqhaza ekwakhiweni kwezingqimba, futhi anqume ukuthi yiziphi izindawo zamap lipids kakhulu. Inqubo yokufaka ama-acidi e-oleic ku-lipids ehlanganisa izingxube ze-biological namanye ama-fatty acids aguqule ngokuphawulekayo isici sezinto eziphilayo ze-membrane, okuthiwa i-permeability. Ukutholakala kwamanani amaningi e-acids emafatsheni ezitolo zomuntu ezithengayo kuhlinzeka ukuvikelwa kwe-lipids kusuka kokushukela nge-antioxidants encane.
I-oleic acid, ngokuyisisekelo, i-fatty acidable replaceable engakwazi ukuhlanganiswa, isibonelo, emangqamuzaneni esibindi somuntu. Kodwa i-oleic acids, nakho konke lokhu, ingenye ye-acids ejwayelekile etholakala kumafutha okudla. I-oleic acid idlala indima enkulu ekudleni kwabantu. Amafutha, lapho okuqukethwe kwe-oleic acid kukwandiswa khona, kudla kakhulu. Kuzokwelapha, ngisho nokusetshenziswa kokwelashwa kusetshenziswa, ngesisekelo lapho i-oleic acid i-linetol.
Embonini, i-oleic acid isetshenziselwa ukukhiqizwa kwezembatho, ama-varnishes, ama-drying, ama-enamel, amapende. Ibuye isetshenziswe njengezinto zepulasitiki ezenziwe ngamafutha, kanye nosawoti walo - ezithombeni.
Le asidi iyimithombo yamandla emzimbeni, njengamanye ama-acid acids. Amandla akhishwa yi-oxidation yama-oleic fatty acids emva kokuhlukaniswa kwawo kumangqamuzana we-lipid ngaphansi kwesenzo sama-pancreatic. Ukuhlanganiswa kwala ma-acids kuhloswe nge-enzyme ekhethekile ebizwa ngokuthi i-oxygenase, ekhona kuma-tissu amafutha nesibindi.
Ama-oleic acids atholakala emafutheni omnqumo ngesikhathi se-crystallization amaningi ngemva kokuphazamiseka kwe-lipids. Ukuzimisela okwenziwe ngokweqile nokwenelisa i-oleic acid kwenziwa yi-gas-liquid chromatography.
Inani le-oleic acid emndenini wesintu.
Ngamafutha ezilwane, ama-oleic acid abiza cishe ama-40% we-value yawo wonke ama-acids, futhi cishe kuwo wonke amafutha yemifino - cishe ama-30%. Ecebile kakhulu e-oleic acids, amafutha omnqumo namafutha e-peanut.
I-oleic acid iyashintshashintsha, naphezu kokuthi ekudleni komuntu kubhekwa njengokuqukethwe okuhle kakhulu, okuyinto esondelene kakhulu nokuqukethwe okugcinwe ngamafutha abantu. Yilokho okuvimbela isidingo sokuvuselela ukwakhiwa kwe-fatty acid ye-lipids ezayo ngokudla, okusho ukuthi ngeke kube khona ukungcola okungadingekile kwemithombo namandla emzimbeni womuntu.
Ukudla okune-oleic fatty acids ngokudla kunikezwa ngokubheka amafomula wokudla okunomsoco, okusho ukuthi ekudleni komuntu okungenani kwezintathu zamafutha kufanele kube yisilwane, futhi isithathu semvelaphi yemifino. Kulesi simo, ukudla kuzoba ne-40% yama-oleic acid. Ngemuva kokwelashwa kwamafutha okucebile ama-acidi e-oleic, azincishiswa kancane nge-oxidation kunamanye amafutha. Lesi yisisekelo sokusetshenziswa kwamafutha ekutholeni imikhiqizo ethile evela kummbila, amazambane, njll, kanye nokuthulula ukudla okusemathinini.
Ngemuva kwe-hydrogenation yamafutha yemifino, ama-ac-oleic acids akha ukukhiqiza ama-margarine amafutha. Le isomerom, njenge-oleic acids, ifakwe emzimbeni womuntu, kodwa encane kakhulu endaweni yesifo se-fat.
Amakhemikhali e-oleic abalulekile ekusetshenzisweni kwemithi efanele.
