I-Anthocyanins kanye ne-proanthocyanidins yizigaba ezimbili zezinhlanganisela zezitshalo ezithole ukunakwa kwezinzuzo zazo zezempilo ezingaba khona kanye nezakhiwo ze-antioxidant.Ngenkathi bebelana ngokufana okuthile, baphinde babe nomehluko ohlukile ngokuya ngesakhiwo samakhemikhali wabo, imithombo, kanye nemiphumela yezempilo engaba khona.Ukuqonda umehluko phakathi kwalezi zinhlanganisela ezimbili kunganikeza ukuqonda okubalulekile endimeni yazo eyingqayizivele ekukhuthazeni impilo nokuvimbela izifo.
Ama-Anthocyaninsziyimibala encibilikayo emanzini eyingxenye yenhlanganisela ye-flavonoid.Banesibopho sombala obomvu, onsomi, noluhlaza okwesibhakabhaka ezithelweni eziningi, imifino, nezimbali.Imithombo yokudla evamile yama-anthocyanins ihlanganisa amajikijolo (njengama-blueberries, ama-strawberries, nama-raspberries), iklabishi elibomvu, amagilebhisi abomvu, nama-eggplant.Ama-anthocyanins aziwa ngezakhiwo zawo zokulwa ne-antioxidant, esiza ukuvikela amaseli emonakalweni obangelwa ama-radicals mahhala.Ucwaningo luye lwaphakamisa ukuthi ama-anthocyanins angase abe nezinzuzo zezempilo ezingaba khona, njengokunciphisa ingozi yesifo senhliziyo, ukuthuthukisa ukusebenza kwengqondo, nokuvikela ezinhlotsheni ezithile zomdlavuza.
Ngokolunye uhlangothi,proanthocyanidinsikilasi lezinhlanganisela ze-flavonoid ezaziwa nangokuthi ama-tannins ajiyile.Atholakala ekudleni okuhlukahlukene okusekelwe ezitshalweni, okuhlanganisa amagilebhisi, ama-apula, ukhokho, nezinhlobo ezithile zamantongomane.Ama-Proanthocyanidin aziwa ngekhono lawo lokubopha amaprotheni, okubanikeza izinzuzo zezempilo ezingaba khona njengokusekela impilo yenhliziyo nemithambo yegazi, ukukhuthaza impilo yesikhumba, nokuvikela ekucindezelekeni kwe-oxidative.Ama-Proanthocyanidins nawo ayaziwa ngeqhaza lawo ekukhuthazeni impilo yomgudu womchamo ngokuvimbela ukunamathela kwamagciwane athile olwelweni lomgudu womchamo.
Omunye umehluko oyinhloko phakathi kwe-anthocyanins nama-proanthocyanidin usesakhiweni sawo samakhemikhali.Ama-anthocyanins angama-glycosides e-anthocyanidins, okusho ukuthi aqukethe i-anthocyanidin molecule exhunywe kwi-molecule kashukela.I-Anthocyanidins yizinhlobo ze-aglycone ze-anthocyanins, okusho ukuthi ziyingxenye engeyona ushukela ye-molecule.Ngokuphambene, ama-proanthocyanidin angama-polymers we-flavan-3-ols, akhiwe ngamayunithi e-catechin nama-epicatechin axhunywe ndawonye.Lo mehluko wesakhiwo unomthelela ekuhlukeni kwezakhiwo zabo zomzimba namakhemikhali, kanye nemisebenzi yazo yebhayoloji.
Omunye umehluko obalulekile phakathi kwe-anthocyanins ne-proanthocyanidin ukuzinza nokutholakala kwe-bioavailability.I-Anthocyanins iyinhlanganisela engazinzile engonakaliswa kalula yizinto ezifana nokushisa, ukukhanya, kanye nezinguquko ze-pH.Lokhu kungathinta i-bioavailability yabo kanye nezinzuzo zezempilo ezingaba khona.Ngakolunye uhlangothi, ama-proanthocyanidin azinzile futhi amelana nokuwohloka, okungase kube nomthelela ekutholakaleni kwawo okuphezulu kwe-bioavailability kanye nomsebenzi webhayoloji emzimbeni.
Mayelana nezinzuzo zezempilo, kokubili ama-anthocyanins nama-proanthocyanidins acutshungulwe ngezindima zawo ezingaba khona ekuvimbeleni izifo ezingamahlalakhona kanye nokukhuthaza impilo yonke.I-Anthocyanins iye yahlotshaniswa nemiphumela elwa nokuvuvukala, elwa nomdlavuza, kanye ne-neuroprotective, kanye nezinzuzo zenhliziyo njengokuthuthukisa ukusebenza kwemithambo yegazi nokunciphisa ingozi ye-atherosclerosis.I-Proanthocyanidins iye yaphenywa ngenxa yezakhiwo zayo zokulwa ne-antioxidant, anti-inflammatory, kanye ne-anti-microbial, kanye namandla ayo okusekela impilo yenhliziyo nemithambo yegazi, ithuthukise ukunwebeka kwesikhumba, futhi ivikele ekunciphiseni kwengqondo okuhlobene nobudala.
Kubalulekile ukuqaphela ukuthi imiphumela yezempilo ye-anthocyanins kanye ne-proanthocyanidins isacwaningwa ngenkuthalo, futhi ucwaningo olwengeziwe luyadingeka ukuze kuqondwe ngokugcwele izindlela zabo zokwenza kanye nezicelo zokwelashwa ezingase zibe khona.Ukwengeza, i-bioavailability kanye ne-metabolism yalezi zinhlanganisela emzimbeni womuntu ingahluka ngokuya ngezinto ezinjengomehluko ngamunye, i-matrix yokudla, nezindlela zokucubungula.
Sengiphetha, i-anthocyanins kanye ne-proanthocyanidins ayizigaba ezimbili zezinhlanganisela zezitshalo ezinikeza uhla lwezinzuzo zezempilo ezingaba khona ngenxa yezakhiwo zazo zokulwa ne-antioxidant ne-bioactive.Nakuba babelana ngokufana okuthile ngokwemiphumela yabo ye-antioxidant kanye nezinzuzo zezempilo ezingaba khona, futhi banomehluko ohlukile ekwakhekeni kwamakhemikhali abo, imithombo, ukuzinza, kanye nokuba khona kwe-bioavailability.Ukuqonda izici eziyingqayizivele zalezi zinhlanganisela kungasisiza ukuba sazise izindima zazo ezihlukahlukene ekukhuthazeni impilo nokuvimbela izifo.
