Korakenahe wāhanga nui o te pūtau i waho o te pūtau (ECM), e kitea nuitia ana i roto i te kiri tangata, i ngā wheua, i te kiriuhi, i ngā niho, i ngā uaua, i ngā hononga, me ngā uaua toto. He pūmua hanganga nui anō hoki mō te kiko honohono.

He wāhanga nui te korarane o te kiri tangata. Me te iti o te elastin, ka hangaia he whatunga pūmau o ngā muka korarane, e hoatu ana ki te kiri he ngāwari me te pakari, ā, ka taea e te paparanga epidermal te kawe i te makuku.

Heoi, ko ngā āhuatanga pēnei i te koroheketanga, te hihi UV, te momi hikareti, me ngā momo noho kino ka heke ai te collagen. Ina ngaro te collagen i roto i te nui, ka puta haere ngā tohu o te koroheketanga pēnei i te ngaronga o te ngāwari o te kiri, te whakaheke, ngā kita, te tae kiri, te maroke, te kiri taratara, me te kiri tairongo.

Nā, i te hekenga o te collagen, ka taea e ngā hua collagen ā-waha te whakaroa i te tukanga koroheketanga?

Ka taea e te tinana te mimiti i ngā peptide collagen mā te waha?

Ko ngā hua collagen e kitea ana i te mākete e pā ana ki ngā peptide collagen, ehara i te collagen.

KorakenaKo ngā peptide he ranunga o ngā peptide taumaha ngota iti me te taumaha ngota toharite o te 2000 ki te 10,000 Da i whakawhaiatia mai i te collagen (300,000 Da). Ki te whakatauritea ki te collagen taumaha ngota teitei, he iti ake te taumaha ngota o ngā peptide collagen, ā, he ngāwari ake te nakunaku me te mimiti.

Hei tāpiritanga, ko ngā dipeptides me ngā tripeptides kei roto i ngā peptides collagen ka haria tikatia, ka mimitia hoki hei peptides e te pūmua kawe oligopeptide (PepT1) kei roto i ngā pūtau epithelial o te whekau iti. Ka taea te arotahi ki ngā wāhi motuhake o te tinana mō te mahi koiora me te whai huatanga.

I horomia e Watanabe-Kamiyama M. me ētahi atu ngā peptide collagen kua tohua ki te 14C ki roto i ngā momo whekau o ngā kiore, ā, i tirohia te tohatoha ongā peptides collagen.

I whakaatuhia e te rangahau i muri i te nakunaku me te mimiti o te kai, ka tohatohahia ngā peptide collagen ā-waha ki ngā whekau nui puta noa i te tinana, ā, ka whakatakotoria ki roto i ngā kiko whai kiko o te collagen, inā koa te kiri, i muri i tētahi wā.

Ka taea e ngā peptide collagen ā-waha te whakapai ake i ngā āhuatanga kiri?

I ngā tau tata nei, kua nui haere ngā rangahau kua whakaū i ngā hua pai o ngā peptide collagen ā-waha ki te whakaroa i te koroheketanga o te kiri me te whakaora i te kiri.

I tīpakohia e ngā kairangahau ētahi tūao 64 i waenga i te 40 me te 60 tau te pakeke ki te tango i te 1000 mg o ngā peptide collagen taumaha-iti i te waha i ia rā mō ngā wiki 12, ā, i kitea i muri i te 6 wiki o te kai, i tino pai ake te makuku o te kiri, ā, i muri i te 12 wiki, i pai ake ngā kita me te ngāwari o te kiri, e whakaatu ana i ngā pānga ārai-pakeketanga. I whakaatuhia e ngā hua he whakapainga nui o te pupuri makuku o te kiri i muri i te 6 wiki o te kai me te pānga ārai-pakeketanga i muri i te 12 wiki.
