• Kev noj zaub mov koom nrog thiab ntau dhau
• Cov kab mob cia
• Piv txwv ntawm lipid
• Xav paub ntxiv?

Cov lipid Lawv yog ib feem ntawm txhua tus neeg noj zaub mov, tshwj xeeb yog feem uas feem ntau muab los ntawm cov rog, uas ua ke nrog cov carbohydrates sawv cev rau qhov loj tshaj plaws ntawm lub zog rau lub cev.

Cov lipid Lawv yog cov organic molecules uas tau tsim los ntawm cov pa roj carbon thiab hydrogen, thiab nws tus yam ntxwv tseem ceeb yog tias lawv tsis yaj hauv dej tab sis yaj hauv lwm tus. cov organic sib txuas zoo li benzine thiab chloroform.

Lawv ua tiav dab tsi?

Hauv qhov kev nkag siab no, nws tuaj yeem hais tau li ntawd lub luag haujlwm tseem ceeb ntawm lipid yog nquagLawv yog txoj hauv kev zoo los khaws lub zog: lawv cov ntsiab lus caloric yog 10 kilocalories ib gram.

Txawm li cas los xij, lipid tseem muaj lub luag haujlwm hauv lub cev ib yam Dej tseg, vim tias lawv muaj kev txo qis ntau dua li cov carbohydrates.

Ntawm qhov tod tes, cov cua sov cia Nws kuj tseem yuav ua nrog lipid, nrog rau ntau yam txheej txheem, qhia paub lossis catalytic ntawm lub cev.

Kev faib tawm ntawm lipid thiab cov rog

Kev faib tawm ntau tshaj plaws ua los ntawm lipid yog nruab nrab ntawm saponifiables thiab cov tsis saponifiable: cov qub tau muab coj los ua ke ntawm cov kab mob los ntawm kev ua tiav ntawm kev faib ua ob pawg ntawm cov pa roj carbon atoms, thaum tom kawg yog sib xyaw los ntawm cov hauv paus yooj yim ntawm tsib carbon atoms.

Nyob rau hauv pab pawg ntawm saponifiables yog cov rog rog, uas nyob rau hauv lem feem ntau yog cais ntawm saturated thiab unsaturated. Cov Cov rog yog cov uas muaj tsiaj keeb kwm, thaum cov rogtsis txaus lawv yog cov uas tawm los ntawm cov zaub, thiab muaj kev noj qab haus huv siv thaum hloov cov zaub uas tau siav.

Kev noj zaub mov koom nrog thiab ntau dhau

Txog kev noj zaub mov ntawm tib neeg, nws tau pom zoo tias cov rog pab nruab nrab ntawm nees nkaum thiab peb caug feem pua ntawm kev xav tau lub zog txhua hnub.

Txawm li cas los xij, lub cev tsis siv sib npaug ntawm txhua hom rog, yog li nws zoo dua hais tias lub cev yuav tsum muaj 10 feem pua ​​ntawm cov rog rog, 5 feem pua ​​cov rog tsis rog, thiab 5 feem pua ​​polyunsaturated rog.

Yog tias koj haus ntau ntau cov rog ntau dua li qhov pom zoo, feem ntau nws yuav yog qhov ntxiv nrog kev noj lwm yam cov as -ham koj ua tiav dhau qhov kev txwv cov calories uas tau pom zoo. Yog tias, qhov hloov pauv, dab tsi tshwm sim yog a noj ntau dhau ntawm cov rog rog, Dab tsi nce yog qhov pheej hmoo ntawm cov kab mob plawv.

Cov kab mob cia

Ntawm qhov tod tes, muaj ob peb kab mob uas tuaj yeem tshwm sim los ntawm kev khaws cov lipid hauv qee qhov hlwb thiab cov ntaub so ntswg ntawm lub cev.

Feem ntau yog kab mob kab mob, uas yog tshwm sim los ntawm kev tsis txaus hauv cov enzyme glucocerebrosidase, thiab cuam tshuam rau txiv neej thiab poj niam sib npaug. Lwm yam kab mob ntawm hom no yog cov Niemann-Pick, Fabbry's lossis gangliosidosis.

Tag nrho cov kab mob no yog caj ces, txij li cov niam txiv nqa cov noob tsis zoo ntawd tswj cov protein tshwj xeeb hauv chav kawm ntawm lub cev. Txawm hais tias kev kho tus kab mob no ntau zaus tseem tsis tau muaj, a kev hloov kho enzyme, lossis tso ntshav.

Piv txwv ntawm lipid

Cov npe hauv qab no tseem suav nrog cov zaub mov uas muaj lipid-muaj:
