Lub ntsiab muaj nuj nqi ntawm lipids, lawv tseem ceeb mus rau lub zuag qhia tag nrho cov metabolism hauv

Lipids yog complex tebchaw, uas muaj xws li ntau dua fatty acids thiab esters. Lawv tsis yaj nyob rau hauv dej, tab sis tsuas nyob rau hauv cov organic solvents. Lub ntsiab functions ntawm roj - ntxwv thiab ntxawg, raws li zoo raws li muab lub cev nrog lub zog.

Cov yam ntxwv lub luag hauj lwm ntawm lipids yog hais tias lawv lub hauv paus ntawm cell week. Lub ntxawg muaj nuj nqi ntawm lipids - muab daim nyias nyias permeability thiab receptor system uas tso cai rau koj los ua rau catecholamine hlwb, acetylcholine, raws li zoo raws li insulin thiab cytokines. Tsis tas li ntawd, cov rog muab colloidal lub xeev ntawm cell week, lawv fluidity thiab cov kev ua ntawm tej yam enzymes, xws li cytochrome oxidase, guanylate cyclase, ATPase. Ib tug cais hom lipid (BAS), uas muaj xws li cov steroid cov tshuaj hormones, leukotrienes thiab platelet-activating tau muaj peev xwm sawv ntawm regulating lub lag luam tsis tsuas yog ntawm ib tug neeg lub hlwb, tab sis kuj ntawm ntaub so ntswg thiab kabmob.

Options xws li lipid lawv lub luag hauj lwm nyob rau hauv lub cev lub zog, uas yog siv rau cov nqaij contraction, nyob rau hauv lub hauv nruab nrog cev, tshwj xeeb yog lub raum thiab lub siab, raws li zoo raws li nyob rau hauv paj dab.

Nws yuav tsum tau muab sau tseg tias muaj nuj nqi ntawm lipids yog zoo txog rau lawv cov qauv. Lawv yog zoo thiab ntau pes tsawg leeg muab cov nuj nqi ntawm lub hlwb thiab lawv cov kev ua. Piv txwv li, cov daim nyias nyias phospholipids yuav cuam tshuam rau cov protein ntau transporters thiab ion raws, thiab cov kev hloov nyob rau hauv lawv cov chaw ua hauj lwm yuav ib tug ua txhaum ntawm lub zog ntawm lub hlwb thiab lub cev tag nrho.

Sibhawm yog tseem ceeb heev tshuaj. Nyob rau hauv tas li ntawd mus rau cov kev khiav dej num, lawv kuj muab kev koom tes nyob rau hauv thermoregulation, raws li cov neeg pluag conductors ntawm tshav kub. Uas yog vim li cas lub subcutaneous roj puag pab lub cev khaws thaum tshav kub kub. Peb kuj yuav tsum hais tias lub cev muaj roj muaj cushioning zog, li ntawd, nws muaj peev xwm los tiv thaiv lub hauv nruab nrog cev (piv txwv li, lub raum) los ntawm cov neeg kho tshuab kev puas tsuaj, txawm hais tias nws ntau heev yuav muaj ib tug tsis zoo feem nyob rau hauv lawv ua hauj lwm, uas yog feem ntau cai nyob rau hauv yuam cai ntawm lipid metabolism, xws li rog.

Lub catalytic muaj nuj nqi ntawm lipids txuam nrog fat-soluble vitamins, uas yog ib feem ntawm ntau enzymes. Sibhawm kuj yog ib qhov chaw ntawm metabolic dej vim hais tias thaum lub sij hawm lub oxidation ntawm cov tshuaj tsim dej. Lawv yog cov tseem yog ib feem ntawm sebum, uas tiv thaiv ntev dryness ntawm cov tawv nqaij.

Muab qhov tseem ceeb lom luag hauj lwm ntawm rog, koj yuav tsum kom lawv tau noj nyob rau hauv txaus qhov ntau. Ib tug tseem ceeb qhov chaw ntawm cov tebchaw yog tsiaj cov khoom, ntses, ceev, zaub roj, khoom noj siv mis thiab cov qe qe.

Rog metabolism hauv tib neeg lub cev nyob ntawm ntau yam. Nyob rau hauv cov ntaub ntawv ntawm kev ua txhaum cai ntawm ib qho ntawm cov ntaub ntawv tsim units metabolism ntawm ntau yam pathological tej yam kev mob thiab cov kab mob - rog, wasting, lipodystrophy los yog lipidoses. Nyob rau hauv lub pathogenesis ntawm txoj kev loj hlob dua pw mob ntawm kev zom thiab nqus roj, impaired lawv transmembrane thauj, raws li zoo raws li metabolic kev hloov nyob rau hauv lub cell.

Cov pathologies yog yus muaj los ntawm tej kev soj ntsuam ces, ua txhaum cov kev mob ntawm tus neeg thiab yuav tsum tau raws sij hawm mob thiab kev kho mob.
