Umsebenzi oyinhloko lipids, ukubaluleka kwabo umzimba jikelele

Lipids kukhona compounds eziyinkimbinkimbi, okuyinto zihlanganisa ephakeme acid okunamafutha kanye esters. Abanaso chaza emanzini, kodwa kuphela ezihogelwayo. Imisebenzi esemqoka amafutha - kwesakhiwo zokulawula, kanye nokunikeza umzimba amandla.

Iqhaza isakhi lipids ngukutsi yisisekelo cell ulwelwesi. Umsebenzi lelawula lipids - ukuhlinzeka ulwelwesi permeability kanye yokwamukela uhlelo elikuvumela ukuba isinyathelo catecholamine amaseli, acetylcholine, kanye insulini kanye cytokines. Ngaphezu kwalokho, amafutha ukuhlinzeka isimo colloidal of cell ulwelwesi, fluidity yabo futhi umsebenzi enzyme ethile, njengengcebo cytochrome oxidase, guanylate cyclase, ATPase. Uhlobo ehlukile lipid (BAS), ezifaka hlangana ukuhlahluba hormone steroid, leukotrienes futhi platelet-isebenze isici uyakwazi olawula ukusebenza nje kuphela amangqamuzana ngamanye, kodwa futhi kwezicubu eziyishumi nemitshingo.

Izinketho zibandakanya lipid indima yabo namandla omzimba, esetshenziselwa imisipha, e izibilini, ikakhulukazi izinso futhi isibindi, kanye nerve izinqubo.

Kumele kuqashelwe ukuthi umsebenzi lipids ihlobene eduze isakhiwo sabo. Ukwakheka yabo lesifanele qualitative ambalwa inikeza umsebenzi amaseli nemisebenzi yazo. Ngokwesibonelo, phospholipids ulwelwesi kungathinta abathutha amaprotheni neziteshi ion, futhi izinguquko umsebenzi wabo kuhilela ukuhlukumeza imisebenzi amaseli bese umzimba wonke.

Amafutha kukhona esibalulekile izinto. Ngaphezu kwalezi imisebenzi, benza zihilelekile thermoregulation, njengoba babashayeli abampofu ukushisa. Yingakho base amafutha ongama kusiza umzimba ukugcina ukushisa. Kumelwe futhi bathi fat umzimba has cushioning izakhiwo, ngakho-ke uyakwazi ukuvikela kwezitho zangaphakathi (isib, izinso) ekulimaleni mechanical, nakuba ngokweqile yayo ungaba nethonya elibi endleleni umsebenzi wabo, okuyinto evame kakhulu waphawula ayephuli lipid umzimba, ezifana ukukhuluphala.

Umsebenzi okhanda amanye amathuba lipids elihlobene ne amavithamini fat-encibilikayo, okuyizinto ingxenye enzyme eziningi. Amafutha nawo umthombo wamanzi umzimba ngoba ngesikhathi namachibi zezinto amanzi kwakhiwa. Futhi ingxenye sebum, okuyinto kuvimbela ukoma ngokweqile kwesikhumba.

Banikezwe indima ebalulekile begazi amafutha, udinga ukuba udle eziningi ezanele. A umthombo owusizo lezi zakhi yilezi imikhiqizo yezilwane, inhlanzi, amantongomane, amafutha yemifino, imikhiqizo yobisi amaqanda izikhupha.

fat umzimba emzimbeni womuntu kuncike ezintweni eziningi. Uma ukwephula eyodwa idatha ekuthuthukiseni amayunithi umzimba izimo ezihlukahlukene sokugembula nezifo - ukukhuluphala, esincunzayo, lipodystrophy noma lipidoses. Esikhathini pathogenesis yentuthuko okungcono amanga iziyaluyalu ukugaya kanye ukumuncwa amafutha, kahle transmembrane ezokuthutha zabo, kanye nezinguquko umzimba ngaphakathi engqamuzaneni.

Lezi pathologies zinezikhathi ukubonakaliswa ethile yomtholampilo, abephula isimo jikelele umuntu futhi zidinga uphethwe ngesikhathi esifanele kanye nokwelashwa.
