Ka halepaahaoʻili lahilahi a me kona liluwelo kūlana

I keia manawa, no ka hapanui kanaka ka mea, mea i ike ole ia i na membranes mea he kī hehee ai i loko o ka rula o ka biochemical keʻano o ka hanaʻana i loko o ka halepaahao. Ma muli o ka liluwelo membranes i kākoʻo 'ia e na homeostasis loko o ka halepaahao. Cellʻili lahilahi vysokoizberatelno hoʻomaʻa i ka mämä holo o ke anal o kela liluwelo i huiʻia i loko o ka halepaahao, e like me ka pono me ke ala mai o nā'ūhū a me transporters. Eia hoʻi, i kēia 'ole i ka luna' liluwelo eiiieaena a 'oi aku i ka pokole, hou' a me ka hoolilo ana o 'ike mai o ka' ia i loko o ka halepaahao.

Ke aeeaʻili lahilahi mea he 'ole i oʻokeʻa keena, a subcellular organelles (lysosomes, mitochondria, Golgi i hoʻomākaukauʻia , etc.). Kēlā me kēia aeea mea he holistic nenoaiie o membranes kūkulu i omo,ʻeke a me poʻina nalu. Na liluweloʻili lahilahi - ka a lahilahi (60-70%) glycoprotein a me ka lipoprotein ano. It E e kaulana ia mea koʻohune, a kanu keena , e like holoholona i hiki ke hoʻololi 'ana i kā lākou mau helehelena e like me ka mea i hoopuniia e ka mānoanoa aeea pā pōhaku. Cell ʻili lahilahi kanu kino ninoieo o polysaccharides, koʻohune o monosaccharides,'amino pulapula o ke, lipids a me'amino nāʻakika.

Ka 'ole o ka halepaahao ʻili lahilahi.

I ka papa kuhikuhiE eiiiiiaiou o aeea membranes i lipids (60-70%) - phosphatidylcholine, phosphatidylethanolamine, sphingomyelin a me ka naʻokoko. Naʻokoko ua pili i ka liluweloʻili lahilahi rigidity, no laila, i kaʻili lahilahi me ka uuku lehulehu o ka naʻokoko oi laholio. ʻili lahilahi nā polokina i hōʻike mai iā ia lipoprotein a glycoprotein eiiieaenu (30-35%). Cellʻili lahilahi i loko o ka liʻiliʻi nui no hoi kekahi mau carbohydrates like hapa o glycoproteins, glycolipids a me glycosaminoglycans (5-10%). Ka 'ole o ka halepaahao membranes a me nā nīnūnē i huiʻia (nukelea nāʻakika, antioxidants,'okanikaʻole Ion, coenzymes, etc.). Wai kokoʻili lahilahi i pili loa, a pau o ia me ka intracellular membranes o ka endoplasmic reticulum (reticulum). Ka haku mele 'ana nā reticulumʻili lahilahi granular a agranular endoplasmic reticulum, i mahele i ka pā a puni i loko o ka iiiaanoaa o ka halepaahao compartments. Ua mea o ka nui i loko o ka rula o intracellular amo o ka waiwai a me ka pele o metabolic keʻano o ka hanaʻana.

I ka hana o ka halepaahaoʻili lahilahi.

Cell membranes i ka'ākeʻakeʻa mai papa, i hoike mai ai ia ia iho i loko o ka palapala o ka e wae, e hoʻomalu aku pūnao me ke kaiapuni. Ma e wae permeability i loko o ka halepaahao hiki ke komo wale 'ona o ka kekahi nui.

Biomembrane amo papa hoʻolako i ka hoolilo ana o māhuaola i loko o ka halepaahao a me ka wehe 'ia o ka hope metabolites mau mea. Ke aeeaʻili lahilahi e komo i loko o ka malama ana i ka pono ai pH. O na hui a i ole hiki ke kea bilipidny, ahu iho, e komo ma kekahi lawe nā polokina, a ma ka endocytosis. Ka OEʻano transprorta 'ona i loko o aeee nā maholahune. Kaʻeleu amo o ka waiwai ua lawe mai i ke komo o ka potasiuma-paʻakai EII ni.

Muaʻili lahilahi hana, kena ae la ia e kekahi interposition, a kohoʻia o kaʻili lahilahi nā polokina. Nui kūlana ma ka hōʻoia 'ke ÿano mana i aeea pā, a me nā holoholona - intercellular waiwai. Ka papa mea loaʻa ua hana ma muli o ia i ke alo o ka kūikawā nā polokina e i IIeEeAIEUIeXAIIUE ai i ka halepaahaoʻili lahilahi.

Ke enzymatic hana o liluwelo membranes pili me kaʻili lahilahi nā polokina a me nā'ūhū. No ka laʻana, i ka wai koko membranes o epithelial aeee (epithelial keena o ka liʻiliʻi) komo digestive nā'ūhū.
