Lipids - he aha te mea te reira? Lipids: mahi, ngā āhuatanga

Lipids - he aha te mea te reira? I roto i Kariki, i te kupu "lipids" tikanga "matūriki iti o te ngako." Ko ratou he rōpū o pūhui tūturu o matū āhua organic whānui kei tika ngako me te ngako-rite. He wāhanga o nga pūtau ora kotahi ratou me kua wehea ki ngā kāwai ohie, me te uaua. Ko te hanganga o te lipid ohie ngā waipiro me te fatty waikawa, a ka i roto matatini teitei wae taimaha rāpoi. E pā ana rua ki kiriuhi koiora, i te pānga i runga i te whākōkī kaha, ka whai wāhi hoki i roto i te hanganga o te ponana karere e whakaongaonga uaua hukihuki.

Fats me hydrophobia

Ko tētahi o nga mahi o lipids ko te hanga o te rahui pūngao o te rauropi, me ki te whakarite te kaiutuutu repelling āhuatanga o te kiri, i honoa e ki te tiaki mātao waiariki. ngako-kei roto taonga, a kahore ana waikawa ngako etahi, tuku ano ki lipids, hei tauira, sterols reira me terpenes. e kore e taea te whai wāhi lipids ki te reo wai, engari tareka ngā i roto i te wai organic pērā i chloroform, benzene, hauwaiwaro.

Lipids, te whakaaturanga o nei tū te wā i hui ao i roto i te hononga ki ngā āhuatanga hou, he kaupapa memeha mō te ako me te rangahau. Ko te pātai "lipids - he aha te mea te reira?" Te reira i kore mona tona hāngaitanga. Heoi, e kore e te ahunga whakamua pūtaiao tu tonu. Aita i maoro a'e whakakitea e rave rahi waikawa ngako pūrākau, e he hononga biosynthetic ki lipids. Whakarōpū o ngā pūhui matū waro kia uaua no te mea o te ōrite o etahi āhuatanga, engari ki te rerekētanga nui i roto i te tahi atu tawhā. I roto i te nuinga o te wā, kei te hanga i te reira i te rōpū motuhake, a ka ora te pikitia whānui matū e pā ana pāhekoheko tahi.

kiriuhi pūtau

Lipids - he aha te mea te reira i roto i ngā o te whakaaro mahi? Tuatahi o te katoa, he ratou he wāhanga faufaa o ngā pūtau ora me te kopa o vertebrates. Te nuinga tukanga i roto i te tinana puta ki te whai wāhitanga o lipids, hanganga o kiriuhi pūtau, ngatahi me te utu o tohu i roto i te taiao wahopūtau, e kore e horoa ki te waikawa ngako.

Lipids - he aha te mea te reira, ka tirohia i te tūranga o noa puta pūtaiaki taiki, me prostaglandins phosphoinositide? Tenei, runga ake katoa, te aroaro i roto i te wē toto o fatty acids kukū, e he, i whakamāramatanga, he wāhanga motuhake o te hanganga lipid. takoha Nā ki te āhuatanga hydrophobic o te tinana muri te ki te whakaputa i to ratou pūnaha transportation tino matatini. lipids waikawa ngako te nuinga whakawhiti i roto i te matatini ki albumin me lipoproteins e te hunga wairewa i te wai, kei te kawea i roto i te ara mua.

whakarōpū o lipids

Tohatoha o pūhui ki te āhua koiora, i te kāwai - e hāngai ana tenei tukanga e ki etahi o nga take i raro i tautohe. Ka taea te whakaritea lipids i roto i te hononga ki ngā āhuatanga matüora me hanganga ōrite ki ngā kāwai rerekē. akomanga Basic o lipids ngā pūhui ohie, me te uaua.

Na roto noa ngā:

• Glycerides - nga hākawa nonireka o waipiro, me te fatty waikawa o te kāwai rawa.
• Sperm - teitei hākawa waikawa ngako me 2-ngota waipiro.

lipids Matatini:

• pūhui Phospholipid - ki te whakauru o nga wae hauota, glycerophospholipids, ofingolipidy.
• Glycolipids - e kei roto i te papa o waho o te rauropi koiora.
• Steroids - matū kaha tino o te hihinga kararehe.
• ngako Complex - sterols, lipoproteins, sulfolipids, aminolipids, nonireka, waiwaro.

te mahi

ngako lipid mahi rite rauemi mō kiriuhi pūtau. Whai wāhi i roto i te waka o ngā matū i runga i te taha o te tinana. O te ngako tinana i runga i te hanganga lipid tauturu tiaki te tinana i te hauhauaitu. A ani i te mahi o nga penapena pūngao "i roto i te rāhui".

E hāngai rahui ngako i roto i te cytoplasm pūtau i roto i te puka o te rūrūtia. Vertebrates, a te tangata i roto i ngā, i ngā pūtau motuhake - adipocytes, e e taea ki te roto i te rota o te ngako. Te whakatakoto whakaeminga ngako i roto i adipocytes he tika ki whākōkī lipoid.

mahi koiora

Fat Ko e kore noa he puna pono o te pūngao, te reira hoki he tuuraa i āhuatanga, tauturuhia e te koiora. Ko te lipids kupu taea ki te whakatutuki i te maha o ngā āhuatanga whai hua pēnei i te tautauā tūturu o te tinana ranei, hei kōrero, tona mātao. I roto i te rohe o te raki, e āhuatanga e pāmahana iti, kohikohi nga kararehe katoa ngako takoto e te katoa i runga i te tinana whakanoho iho, te kupu te hanga i te paparanga tūturu paruru e rave te mahi o te tiaki waiariki. He nui rawa hoki nga kararehe nui moana tenei: tohorā, walruses, hiri.

Animals e ora i roto i nga whenua wera, ano kohikohi ngako tinana, engari kahore e wehea ratou puta noa i te tinana, a kua hāngai i roto i etahi wahi. Hei tauira, te kamera ngako haere i roto i te koropuku, kararehe i roto i te koraha - i roto i te matotoru, hiku poto. Nature he türanga tupato, me te tika o te ngako me te wai i roto i ngā kaiao ora.

Ko te mahi hanganga o lipids

e pā ana ngā tukanga katoa ki te mahi o te tinana, i raro ki etahi ture. Phospholipids Ko te pūtake o te kahu koiora o kiriuhi pūtau me te cholesterol regulates te fluidity o enei kiriuhi. Ko te kupu, karapotia te nuinga o nga pūtau ora e te membrane wē ki te kahu rua o lipids. mea faufaa no te mahi pūtau noa taua kukū. I roto i te kei tetahi o te microparticle membrane koiora neke atu i te miriona o ngā rāpoi ngota lipid e riro āhuatanga rua: ko rua hydrophobic me hydrophilic ratou. Ka rite ki te tikanga, he āhuatanga tāuke o te natura nonequilibrium enei, a reira ko rawa arorau ratou taumahinga. Ko te lipids i roto i te pūtau - ko te mana tūturu whai hua. Kei te nuinga te paparanga hydrophobic nuinga e membrane pūtau me tiaki ki te kătahi o katote kino.

Glycerophospholipids, phosphatidylethanolamine, phosphatidylcholine, whai wāhi hoki cholesterol ki te impermeability o te pūtau. Kei te tū te hanganga papanga atu lipids membrane, sphingomyelin me he sfingoglikolipid. Ia taonga he mahi motuhake.

Lipids i roto i te kai tangata

Pāhare - ngako pūāhua kūpapa, he he puna whai hua o te pūngao. fatty kukū waikawa i te kai, me te miraka hua. He waikawa ngako, engari hamanga kitea i roto i nati, putirā me te hinu oriwa, witi purapura me purapura. Na e kore e whakaara te tinana taumata cholesterol, e tūtohu ana he iti ki te 10 ōrau täkupu rā o ngako kararehe.

Lipids, me warowaihā

He maha kaiao kararehe "tāpae" ngako i roto i etahi ngā, te kiko subcutaneous, i roto i nga taiepa o te kiri, me ētahi atu wāhi. He puhoi hāora o lipids taua ngako, a na reira ka taea te tukanga o ratou hurihanga ki te hauhā me te wai waro ki te whiwhi i te nui nui o te pūngao, ko te tata rua ngā wā neke atu i taea te hoatu warowaihā. I tua atu, ko te āhuatanga hydrophobic o ngako faaore i te hiahia o te whakamahi i te rahinga nui o te wai ki te whakatenatena hydration. puta Awatea wāhanga ngako i roto i te pūngao "maroke." Heoi e nui pōturi i roto i ngā o te tuku pūngao ngako, a ka he atu hāngai mō te kararehe i roto i te āhua o te moetanga. Lipids me te warowaihā pērā i kīnaki tahi i te tahi i roto i te tukanga o te kaiao.
