Okuqukethwe
Lapho sibheka isihloko samafutha, sathola ukuthi ama-lipids ayingxenye yamandla emizimbeni yethu. Manje sizokhuluma ngama-phospholipids, nawo angamafutha. Kodwa-ke, esikhundleni sokwengezwa okukodwa kwe-fatty acid ku-alcohol ye-polyatomic, i-phosphorus nayo ikhona kumakhemikhali amakhemikhali e-phospholipids.
Ama-phospholipids ahlukaniswa okokuqala ngoDisemba 1939. Ubhontshisi weSoya kwakungumthombo wawo. Umsebenzi oyinhloko we-phospholipids emzimbeni uhlotshaniswa nokubuyiselwa kwezakhiwo zeselula ezilimele, ngenxa yalokho ukuvinjelwa okujwayelekile kwamaseli kuvinjelwe.
Njengamanje ezinye izidakamizwa ezikhangiswa kabanzi zokubuyisela isibindi zinomphumela wazo wokwelapha ngokunembile ngenxa yokuba khona kwama-phospholipids amahhala ekwakhiweni kwawo. Ngendlela, i-lycetin nayo ingeyaleli qembu le-lipids.
Ukudla okunokuqukethwe okuphezulu kakhulu kwe-phospholipid:
Izici ezijwayelekile ze-phospholipids
I-Phospholipids yizinhlanganisela eziqukethe ama-acid okunama-polyhydric alcohols ne-phosphoric acid. Ngokuya ngokuthi i-polyhydric alcohol iyisisekelo se-phospholipid, umehluko wenziwa phakathi i-glycerophospholipids, i-phosphosphingolipids ne-phosphoinositides… Isisekelo se-glycerophospholipids i-glycerol, ye-phosphosphingolipids - i-sphingosine, nangama-phosphoinositides - inositol.
I-Phospholipids ingeyeqembu lezinto ezibalulekile ezingenakubuyiselwa kubantu. Azivezwa emzimbeni ngakho-ke, kufanele zingeniswe ngokudla. Omunye wemisebenzi ebaluleke kakhulu kuyo yonke i-phospholipids ukubamba iqhaza ekwakhiweni kwezingqamuzana zeseli. Ngesikhathi esifanayo, amaprotheni, ama-polysaccharides namanye ama-compounds awanikeza ukuqina okudingekayo. I-Phospholipids itholakala ezicutshini zenhliziyo, ubuchopho, amaseli ezinzwa nesibindi. Emzimbeni zihlanganiswa nesibindi nezinso.
Imfuneko yansuku zonke ye-phospholipids
Isidingo somzimba se-phospholipids, ngokuya ngokudla okunomsoco, sisuka ku-5 kuye ku-10 amagremu ngosuku. Ngesikhathi esifanayo, kuyinto efiselekayo ukusebenzisa i-phospholipids, ngokuhlanganiswa nama-carbohydrate. Kule nhlanganisela, zithathwa kangcono.
Isidingo se-phospholipids siyanda:
- ngokubuthaka kwememori;
- Isifo i-Alzheimer;
- ezifweni ezihambisana nokwephula ulwelwesi lweseli;
- ngomonakalo onobuthi esibindini;
- nge-hepatitis A, B no-C.
Isidingo se-phospholipids sincipha:
- ngomfutho wegazi ophakeme;
- ngezinguquko zemithambo yegazi e-atherosclerotic;
- ezifweni ezihambisana ne-hypercholemia;
- ngezifo zamanyikwe.
Ukufana kwe-Phospholipid
Ama-phospholipids amuncwa kangcono kanye nama-carbohydrate ayinkimbinkimbi (okusanhlamvu, isinkwa se-bran, imifino, njll.). Ngaphezu kwalokho, indlela yokupheka inomthelela obalulekile ekufakweni okuphelele kwe-phospholipids. Ukudla akufanele kuvezwe ekushiseni isikhathi eside, ngaphandle kwalokho ama-phospholipids akhona kuwo abhujiswa futhi awasakwazi ukuba nomthelela omuhle emzimbeni.
Izakhiwo eziwusizo ze-phospholipids nomphumela wazo emzimbeni
Njengoba kushiwo ngaphambili, i-phospholipids inesibopho sokugcina ubuqotho bezindonga zeseli. Ngaphezu kwalokho, zivuselela ukwedlula kokujwayelekile kwezimpawu ezihambisana nemicu yezinzwa ziye ebuchosheni nasemuva. Futhi, i-phospholipids ingavikela amaseli wesibindi emiphumeleni eyingozi yamakhemikhali.
Ngaphezu kwemiphumela ye-hepatoprotective, enye ye-phospholipids, i-phosphatidylcholine, ithuthukisa ukunikezwa kwegazi ezicutshini zemisipha, igcwalisa imisipha ngamandla, iphinde inyuse ithoni nokusebenza kwemisipha.
I-phospholipids ibaluleke kakhulu ekudleni kwabantu asebekhulile. Lokhu kungenxa yokuthi banemiphumela ye-lipotropic ne-anti-atherosclerotic.
Ukusebenzisana nezinye izinto
Amavithamini amaqembu A, B, D, E, K, F amuncwa emzimbeni kuphela uma ehlangene ngokuvumelana namafutha.
Ukweqiwa kwama-carbohydrate emzimbeni kuqinisa ukuwohloka kwamafutha angasetshenziswanga.
Izimpawu zokushoda kwe-phospholipids emzimbeni:
- ukukhubazeka kwememori;
- isimo sokucindezeleka;
- imifantu ezinhlakeni zomlomo;
- amasosha omzimba buthakathaka;
- i-arthrosis ne-arthritis;
- ukwephulwa komgudu wamathumbu;
- isikhumba esomile, izinwele, izipikili ezinamafutha.
Izimpawu ze-phospholipids eyeqile emzimbeni
- izinkinga ezincane zamathumbu;
- ukuqina kwegazi;
- ukukhathazeka ngokweqile kwesistimu yezinzwa.
I-Phospholipids yobuhle nempilo
Njengoba i-phospholipids inomphumela wokuvikela kuwo wonke amaseli emzimbeni wethu, ukusetshenziswa kwe-phospholipids kungakhonjwa kusethi yosizo lokuqala. Ngemuva kwakho konke, uma lokhu noma lelo seli lomzimba wethu lilimele, khona-ke umzimba uqobo ngeke ukwazi ukwenza imisebenzi eyabelwe yona. Futhi, ngakho-ke, umuntu angaphupha kuphela ngesimo esihle nokubukeka okuhle. Ngakho-ke, yidla ukudla okuqukethe i-phospholipids futhi ube nempilo!
