The lipids Ke karolo ea lijo tsa motho e mong le e mong, haholo karolo eo hangata e fanoang ke mafura, eo hammoho le lik'habohaedreite e emela mohloli o moholo oa matla bakeng sa 'mele.

The lipids Ke limolek'hule tse entsoeng ka bongata tse entsoeng ka khabone le haedrojene, 'me tšobotsi ea tsona ea mantlha ke hore ha e na metsi ka har'a metsi empa e qhibiliha ho a mang. metsoako ea manyolo joaloka benzine le chloroform.

Li phetha mosebetsi ofe?

Ka kutloisiso ena, ho ka boleloa joalo mosebetsi o ka sehloohong oa lipids o mafolofoloKe tsela e ntle haholo ea ho boloka matla.

Leha ho le joalo, lipids le tsona li na le tšebetso kahare ho mmele joalo ka Polokelo ea metsi, kaha li na le phokotso e kholo ho feta lik'habohaedreite.

Ka lehlakoreng le leng, polokelo ea mocheso E boetse e amana le lipids, hammoho le meralo e fapaneng, tlhaiso-leseling kapa catalytic / Ketso ya ho thusa ya mmele.

Kemiso ea lipids le mafura

Sehlopha se tloaelehileng haholo se entsoeng ka lipids se lipakeng tsa li-saponifiable le e sa hlonepheng: tsa pele li entsoe ka likokoana-hloko tse tsoang likarolong tse latellanang tsa liathomo tse peli tsa carbon, ha tse qetellang li entsoe ka karolo ea motheo ea liathomo tse hlano tsa carbon.

Sehlopheng sa li-saponifiable ho na le mafura a li-acid, tseo hangata li arohanngoang lipakeng tsa tse khotsofatsang le tse sa khotsofatsoang. The Mafura a khotsofatsang ke tse nang le semelo sa liphoofolo, ha mafuraunsaturated / Boetsuwa ba ho tlatsa Ke tse tsoang meroho, 'me li na le ts'ebeliso e ntle ha li kenya tse khathollang.

Ho nka karolo lijong le ho fetella

Bakeng sa lijo tsa batho, ho kgothaletswa hore mafura kenya letsoho lipakeng tsa liperesente tse mashome a mabeli ho isa ho mashome a mararo ea litlhoko tsa matla tsa letsatsi le letsatsi.

Leha ho le joalo, 'mele ha o sebelise mefuta eohle ea mafura ka mokhoa o lekanang, ka hona ho molemo ho re' mele o lokela ho ba le mafura a 10 a mafura, liperesente tse 5 tsa mafura a sa khotsofatsoang, le liperesente tse 5 tsa mafura a polyunsaturated.

Haeba u ja mafura a mangata ho feta kamoo ho khothalelitsoeng, ho ka etsahala hore tlatsetso e sebelisoe le tse ling limatlafatsi u qetella u tlotse moeli o khothaletsoang oa likhalori. Haeba, ho fapana le hoo, se etsahalang ke tšebeliso e feteletseng ea mafura a mangata, Se eketsang kotsi ea mafu a pelo le methapo.

Maloetse a polokelo

Ka lehlakoreng le leng, ho na le mafu a 'maloa a ka hlahang ka lebaka la polokelo ea lipids ho a mang lisele le lisele tsa mmele.

E tloaelehileng ka ho fetisisa ke lefu la gaucher, e bakoang ke khaello ea enzyme glucocerebrosidase, mme e ama banna le basali ka ho lekana. Mafu a mang a mofuta ona ke a Niemann-Pick, Fabbry's kapa gangliosidosis.

Maloetse ana kaofela a lefutso, kaha batsoali ba na le liphatsa tsa lefutso tse nang le sekoli seo e laola protheine haholoholo sehlopheng sa disele tsa mmele. Leha kalafo ea mafu ana maemong a mangata e so fumanehe, a Phekolo ea enzyme, kapa litšelo tsa mali.
