Iipilisi

Umxholo

• Nguwuphi umsebenzi abawenzayo?
• Ulwahlulo lweepids kunye namafutha
• Ukuthatha inxaxheba ekudleni kunye nokugqithisa
• Izifo zokugcina
• Imizekelo yeepids
• Iinkcukacha ezithe xaxe?

Inkqubo ye- iipilisi Ziyinxalenye yokutya komntu wonke, ngakumbi icandelo elihlala linikezelwa amafutha, ethi yona kunye ne iikhabhohayidrethi imele owona mthombo mkhulu wamandla emzimbeni.

Inkqubo ye- iipilisi Ziimolekyuli eziphilayo eziqulathe ikakhulu ikhabhon kunye nehydrogen, kwaye eyona nto iphambili kuyo kukuba ayinyibiliki emanzini kodwa inyibilika kwezinye. iikhompawundi eziphilayo Njenge-benzine kunye ne-chloroform.

Nguwuphi umsebenzi abawenzayo?

Ngale ndlela, kunokuthiwa njalo umsebenzi ophambili wee lipids unamandlaZiyindlela elungileyo yokugcina amandla: umxholo wazo wekhalori ziikhalori ezili-10 ngegrama nganye.

Nangona kunjalo, ii-lipids zinomsebenzi ngaphakathi komzimba njengoko Ugcino lwamanzi, njengoko benesidanga esikhulu sokuncitshiswa kwii-carbohydrate.

Kwelinye icala, i ukugcinwa kobushushu Ikwanxulumene neepids, kunye nolwakhiwo ezahlukeneyo, ulwazi okanye catalytic yomzimba.

Ulwahlulo lweepids kunye namafutha

Uhlobo oluqhelekileyo olwenziwe ngee lipids luphakathi kwe saponifiable kwaye i ayinakuphikiswaIzinto zangaphambili zidityanisiwe kwizinto eziphilayo ezivela kulwakhiwo olulandelelanayo lweeyunithi zeeathom ezimbini zekhabhon, ngelixa ezokugqibela zidityaniswa zivela kwiyunithi esisiseko yeeathom zekhabhoni ezintlanu.

Kwiqela le-saponifiable zi-fatty acids, zona zihlala zihlelwa phakathi kokuhluthiswa nokungafakwanga. Inkqubo ye- Amafutha agcwalisiweyo zezo zinemvelaphi yezilwanyana, ngelixa amafuthaengaqinisekanga Zezo ziphuma kwimifuno, kwaye zinokusetyenziswa okusempilweni xa zibuyisela ezihluthiyo.

Ukuthatha inxaxheba ekudleni kunye nokugqithisa

Ukutya kwabantu kuyacetyiswa ukuba amafutha Igalelo eliphakathi kwamashumi amabini anamashumi amathathu eepesenti yeemfuno zamandla zemihla ngemihla.

Nangona kunjalo, umzimba awusebenzisi ngokulinganayo zonke iintlobo zamafutha, kungoko kungcono ukuthi umzimba kufuneka ube ne-10 yeepesenti ezityebileyo, iipesenti ezi-5 zamafutha angafakwanga, kunye neepesenti ezi-5 zepetroli.

Ukuba usebenzisa inani elininzi lamafutha kunokuba ukhuthazile, kunokwenzeka ukuba isongezelelo kunye nokusetyenziswa kwezinye izondlo uphela ugqitha umda wekhalori ekhuthazwayo. Ukuba, endaweni yoko, kwenzeka ntoni ukusetyenziswa gwenxa kwamafutha apheleleyo, Ukonyuka komngcipheko wezifo zentliziyo.

Izifo zokugcina

Kwelinye icala, kukho izifo ezininzi ezinokubonakala ngenxa yokugcina i-lipids kwezinye iiseli kwaye izicwili zomzimba.

Eyona ixhaphakileyo yile isifo gaucher, ebangelwa kukusilela kwi-enzyme glucocerebrosidase, kwaye ichaphazela amadoda nabasetyhini ngokulinganayo. Ezinye izifo zolu hlobo zezi Niemann-Pick, Fabbry's okanye gangliosidosis.

Zonke ezi zifo zezi ilifa, kuba abazali baphethe ufuzo olungalunganga ilawula iprotheni ngakumbi kwiklasi ye iiseli zomzimba. Nangona unyango lwezi zifo kwiimeko ezininzi lingekafumaneki, a Unyango lwe-enzyme, okanye utofelo-gazi.

Imizekelo yeepids

Olu luhlu lulandelayo lukwabandakanya ukutya okune-lipid kakhulu:

Iinkcukacha ezithe xaxe?

• Imizekelo yamafutha
• Imizekelo yeeCarbohydrate
• Iiproteni Imizekelo
• Imizekelo yeeTrace Elements
