Babban aiki na lipids, da muhimmancin da sauran metabolism

Lipids ne hadaddun mahadi, wanda sun hada da mafi girma m acid da kuma esters. Ba su narke a cikin ruwa, amma kawai a cikin kwayoyin kaushi. Babban ayyuka na kitse - tsarin da tsaiko, kazalika da bayar da jiki da makamashi.

A tsarin rawar da lipids shi ne cewa su samar da tushen cell membranes. Dokokin aiki na lipids - samar da membrane permeability da tsoka mai amsa sigina tsarin cewa ba ka damar aiki a kan catecholamine Kwayoyin, acetylcholine, kazalika da insulin da cytokines. Bugu da ƙari kuma, fats samar da colloidal jihar na cell membranes, su fluidity da kuma na ayyuka na wasu enzymes, kamar cytochrome oxidase, guanylate cyclase, ATPase. A raba irin sia (Bas), wanda sun hada da steroid hormones, leukotrienes da platelet-kunna factor iya gudãnar da aiki ba kawai na mutum Kwayoyin, amma kuma daga kyallen takarda da kuma gabobin.

Zabuka sun hada da sia rawar da suka taka a cikin jikin ta samar da makamashi, wanda ake amfani da tsoka ƙanƙancewa, a cikin kayan ciki, musamman na koda da hanta, kazalika a jijiya tafiyar matakai.

Ya kamata a lura da cewa aiki na lipids ne a hankali alaka da tsarin. Su daidai ingantaccen da kuma gwada yawa abun da ke ciki na samar da aiki na sel da su aiki. Alal misali, membrane phospholipids iya shafar gina jiki transporters da ion tashoshi, da kuma canje-canje a cikin aikin ya shafi wani take hakkin da ayyuka na sel da kuma na dukan jiki.

Fats ne m abubuwa. Bugu da kari ga wadannan ayyuka, su ma hannu a thermoregulation, kamar yadda matalauta conductors zafi. Wannan shi ne dalilin da ya sa subcutaneous mai tushe taimaka jiki riƙe zafi. Dole ne kuma mu ce wannan jikin kitsen yana cushioning Properties, don haka shi ne iya kare kayan ciki (misali, koda) daga inji lalacewa, ko da yake ta wuce haddi da zai iya yin mummunan tasiri a kan aikinsu, wanda aka fi akai-akai lura a take hakkin sia metabolism, kamar kiba.

A catalytic aiki na lipids hade tare da mai-mai narkewa bitamin, da su ne a wani ɓangare na da yawa enzymes. Fats ne ma wani tushen rayuwa ruwa saboda a lokacin da hadawan abu da iskar shaka daga cikin abubuwa kafa ruwa. Su ma wani ɓangare na sebum, wanda ya hana wuce kima rashin ruwa da fata.

Ganin muhimmanci nazarin halittu rawar da kitse, ka bukatar su da za a ingested a isa yawa. A muhimmanci da tushen wadannan mahadi dabba da kayayyakin, kifi, kwayoyi, kayan lambu mai, kiwo da samfurori da kuma kwai yolks.

Fat metabolism a cikin jikin mutum ya dogara da yawa dalilai. A hali na take hakkin daya daga cikin data tasowa raka'a metabolism na daban-daban pathological yanayi da kuma cututtuka - kiba, halakarwa, lipodystrophy ko lipidoses.
