Waikawa Phosphatidic. Synthesis me te hiranga i roto i te tinana

Mai i te tirohanga o te hanganga matū, waikawa phosphatidic ko te phospholipid māmā.

Tenei taonga ko tetahi o nga tohu o phosphoglycerides pākia i roto i te vivo.

homai tenei piha o matū e nui aro i roto i te ako o ngā mahi tohu o pūhui matū.

Ki te rā, ki runga ki te mutunga e kore e mārama te hononga katoa i roto i te pākia o waikawa phosphatidic, i roto i ngā, kua whakaaro tonu te pātai o te huarahi o hononga raraunga tohu tuku, me te pā ana ki te aroaro o te waikawa phosphatidic āhuatanga ionophoric.

Synthesis o te waikawa phosphatidic

tākiekina hanganga waikawa Phosphatidic e phospholipase D. tenei piha o whākōkī e te tūranga ārahi i roto i te kōtuitui o ngā waikawa phosphatidic. Ka rite ki te pūhui matū poto ngā-ora, muri te taonga i raro i te mana fosfogidrolazy hāmeha ki diglyceride (i te tauhohenga dephosphorylation).

A, no te pāhekoheko ki te waikawa taua whākōkī phosphatidic taea kia puta me diacylglycerol, e mahi he huringa o matüora mahi tauhohe activator o te kinase C. whākōkī pūmua

Synthesis o waikawa phosphatidic puta i roto i te adipose kiko. haamata te tukanga ki te tango i roto i adipocytes (pūtau kiko adipose) waikawa ngakongako i hanga i roto i te tauhohenga wai o ngako (te nuinga, lipoproteins kiato rawa iti). Roto te pūtau, te pāhekoheko ki te nonireka-tri-Phosphate, kua tahuri tuatahi waikawa ngakongako ki waikawa lysophosphatidic, i nei te waikawa phosphatidic muri i hanga.

i hanga Tātai reira glycerophospholipids phosphoric kei roto toenga o ngā waikawa ngakongako, nonireka, me ng ngota hauota-kei roto.

Meaning o te waikawa phosphatidic

I kitea te reira e te waikawa phosphatidic he pera-ka karanga te hononga kïia, e ko, te hunga e te hunga i te mahi o takawaenga i roto i te tuku o te mōhiohio i roto i te huarahi kē. I roto i ngā, ko reira he hononga matua i roto i te tuku o enei tohu i roto i te tipu ngā pūtau:

• cytokinin;
• osmotic e kua he uara i te whanaketanga o te whakautu pūtau ki tenei ahua o te ahotea.

I roto i ngā i whakakitea ai e faarahi i te taumata o te pūhui i roto i te pūtau kitea ki whakato kaiao āhuatanga pathogenic tino. Tenei tauhohenga ai:

• ahotea osmotic.
• pāmahana iti.
• Ko te pānga o etahi kai kaha he takenga huawhenua (phytohormones).

Ko te kupu, e taea te mutu te reira i runga i te whai wāhitanga o te waikawa phosphatidic me ona metabolites i roto i tauhohe matatini kawenga mō te urutaunga o te kaiao ki āhuatanga taumaha.

I tua atu, kua mohiotia ai e mea faufaa no te te waka o ngā iraoho me te tauhohe o katote konupūmā i roto i nga kiriuhi o neurons me weu uaua te waikawa phosphatidic. Fakatatau ki ai, waikawa phosphatidic me hoki waiho te mahi ionophore (tīpakongia: hoki katote konupūmā me iraoho).

tikanga transduction

Ahakoa kitea tika te whakaaro o te waikawa phosphatidic te tikanga (huarahi) o te tuku tohu e tautohetohe tonu me titau whakatakotoranga.

Heoi kahore he feaa e kawea te transduction i roto i te whakawhetai ki te kaha o te waikawa phosphatidic, e pa ana te hanganga pūtau o te membrane, te membrane whakahaere te mahi o whākōkī, ka whai wāhi hoki i roto i te pāhekoheko ki te rāpoi ngota membrane pūmua pūtau.

Taupānga o te waikawa phosphatidic

Studies i Kua whakaaturia mahi antioxidant o pärönaki o waikawa phosphatidic, whakahaere rite i roto i te ako o te tauira tukanga, me te whai wāhi taonga koiora e riro pera-ka karanga mimetics waikawa phosphatidic plurality antioxidant o tikanga o te mahi.

ngā mōhiohio whānui i runga i te aronga o te mahi o te waikawa phosphatidic e āhei ki te whakamahi i te reira me ona metabolites i te hanga o matū kaha biologically hangaia ki te whakarei ake mahi me te manawanui o ngā pūtau.

Acting i runga i te taumata pūtau, e kore e taua pūhui whakaongaonga, engari haerenga i te pūtau anake; te wāhi nui, ko te ki te whakaiti i te tūpono o ngā pānga kino taha.
