He aha te rerekētanga i waenga i ngā anthocyanin me ngā proanthocyanidin?

Ngā anthocyaninhe tae wairewa-wai ēnei nō te rōpū pūhui flavonoid. Ko rātou te take o ngā tae whero, papura, me te kikorangi i roto i te maha o ngā hua, huawhenua, me ngā putiputi. Ko ngā puna kai noa o ngā anthocyanin ko ngā hua rākau (pērā i te purūpere, te rōpere, me te rāhipere), te kāpeti whero, te karepe whero, me te aubergine. E mōhiotia ana ngā anthocyanin mō ō rātou āhuatanga antioxidant, e āwhina ana ki te tiaki i ngā pūtau mai i te kino i puta mai i ngā rauropi kore utu. Kua whakaarohia e ngā rangahau he painga hauora pea kei roto i ngā anthocyanin, pērā i te whakaiti i te mōrearea o te mate ngakau, te whakapai ake i te mahi hinengaro, me te tiaki i ētahi momo mate pukupuku.

I tētahi atu taha,ngā proanthocyanidinsHe momo pūhui flavonoid ēnei e mōhiotia ana ko ngā tannins whakakōkī. Kei roto i ngā momo kai tipu, tae atu ki ngā karepe, ngā aporo, te koko, me ētahi momo nati. E mōhiotia ana ngā proanthocyanidins mō tō rātou kaha ki te here ki ngā pūmua, e hoatu ana ki a rātou he painga hauora pēnei i te tautoko i te hauora o te ngakau, te whakatairanga i te hauora o te kiri, me te tiaki i te ahotea waikura. E mōhiotia ana hoki ngā proanthocyanidins mō tā rātou mahi ki te whakatairanga i te hauora o te ara mimi mā te aukati i te piri o ētahi huakita ki te ara mimi.

Ko tētahi o ngā rerekētanga matua i waenga i ngā anthocyanin me ngā proanthocyanidin kei roto i tō rāua hanganga matū. Ko ngā anthocyanin he glycoside o ngā anthocyanidin, ko te tikanga he ngota anthocyanidin e piri ana ki te ngota huka. Ko ngā anthocyanidin ngā momo aglycone o ngā anthocyanin, ko te tikanga ko rātou te wāhanga kore-huka o te ngota. He rerekē, ko ngā proanthocyanidin he polymers o te flavan-3-ols, he mea tito mai i ngā wae catechin me ngā wae epicatechin e honoa ana. Ka whai wāhi tēnei rerekētanga hanganga ki ngā rerekētanga o ō rāua āhuatanga ā-tinana me te matū, tae atu ki ā rāua mahi koiora.

Ko tētahi atu rerekētanga nui i waenga i ngā anthocyanin me ngā proanthocyanidin ko tō rātou pumau me te waatea o te koiora. He pūhui kore pumau ngā anthocyanin, ka taea te whakapōrearea ngāwari e ngā āhuatanga pēnei i te wera, te mārama, me ngā huringa pH. Ka pā pea tēnei ki tō rātou waatea o te koiora me ngā painga hauora pea. I tētahi atu taha, he pumau ake ngā proanthocyanidin, ā, he ātete ki te whakapōrearea, ka whai wāhi pea tēnei ki te nui ake o tō rātou waatea o te koiora me te mahi koiora i roto i te tinana.

Mō ngā painga hauora, kua rangahaua ngā anthocyanin me ngā proanthocyanidin mō ō rāua tūranga pea ki te ārai i ngā mate pūmau me te whakatairanga i te hauora whānui. Kua honoa ngā anthocyanin ki ngā pānga ārai-mumura, ārai-matepukupuku, me te tiaki-ira, tae atu ki ngā painga ki te ngākau me te ngākau pērā i te whakapai ake i te mahi a ngā oko toto me te whakaiti i te mōrearea o te atherosclerosis. Kua rangahaua ngā proanthocyanidin mō ō rāua āhuatanga antioxidant, anti-mumura, me te anti-microbial, tae atu ki tō rāua kaha ki te tautoko i te hauora ngākau me te ngākau, te whakapai ake i te ngāwari o te kiri, me te tiaki i te hekenga hinengaro e pā ana ki te koroheketanga.

He mea nui kia mōhiotia kei te rangahauhia tonutia ngā pānga hauora o ngā anthocyanin me ngā proanthocyanidin, ā, me nui ake ngā rangahau hei mārama pai ai ki ngā tikanga mahi me ngā whakamahinga rongoā pea. Hei tāpiri, ka rerekē te bioavailability me te metabolism o ēnei matū i roto i te tinana tangata i runga i ngā āhuatanga pēnei i ngā rerekētanga takitahi, te hanganga kai, me ngā tikanga tukatuka.

Hei whakamutunga, ko ngā anthocyanin me ngā proanthocyanidin he momo matū tipu e rua e tuku ana i ngā painga hauora maha nā ō rātou āhuatanga antioxidant me te bioactive. Ahakoa he rite tonu ō rātou pānga antioxidant me ngā painga hauora pea, he rerekētanga motuhake anō hoki i roto i ō rātou hanganga matū, pūtake, pumau, me te waatea koiora. Mā te mārama ki ngā āhuatanga ahurei o ēnei matū ka āwhina i a tātou ki te mārama ki ō rātou tūranga rerekē ki te whakatairanga i te hauora me te aukati i ngā mate.
