Yintoni umahluko phakathi kwee-anthocyanins kunye nee-proanthocyanidins?

IiAnthocyaninszii-pigment ezinyibilikayo emanzini ezikwiqela lee-flavonoid zeekhompawundi. Zinoxanduva lwemibala ebomvu, emfusa, neluhlaza okwesibhakabhaka kwiziqhamo ezininzi, imifuno, kunye neentyatyambo. Imithombo yokutya eqhelekileyo yee-anthocyanins ibandakanya amaqunube (afana neeblueberries, amastrawberry, kunye nama-raspberries), ikhaphetshu ebomvu, iidiliya ezibomvu, kunye nee-eggplant. Ii-Anthocyanins zaziwa ngeempawu zazo ze-antioxidant, ezinceda ukukhusela iiseli ekonakalisweni okubangelwa zii-free radicals. Izifundo zibonise ukuba ii-anthocyanins zinokuba neengenelo zempilo, ezinje ngokunciphisa umngcipheko wesifo sentliziyo, ukuphucula ukusebenza kwengqondo, kunye nokukhusela kwiintlobo ezithile zomhlaza.

Kwelinye icala,iiproanthocyanidinsziindidi zeekhompawundi ze-flavonoid ezaziwa ngokuba zii-condensed tannins. Zifumaneka kwiindidi ezahlukeneyo zokutya okusekwe kwizityalo, kuquka iidiliya, ii-apile, i-cocoa, kunye neentlobo ezithile zeenati. Ii-Proanthocyanidins zaziwa ngokukwazi kwazo ukubopha kwiiproteni, nto leyo ezinika izibonelelo zempilo ezinokuba nazo njengokuxhasa impilo yentliziyo, ukukhuthaza impilo yolusu, kunye nokukhusela uxinzelelo lwe-oxidative. Ii-Proanthocyanidins zikwaqatshelwa ngendima yazo ekukhuthazeni impilo yendlela yomchamo ngokuthintela ukunamathela kweebhaktheriya ezithile kulwelo lwendlela yomchamo.

Omnye wemiba ephambili phakathi kwee-anthocyanins kunye nee-proanthocyanidins ukwimo yazo yeekhemikhali. Ii-Anthocyanins zii-glycosides ze-anthocyanidins, oko kuthetha ukuba zenziwe yimolekyuli ye-anthocyanidin enamathele kwimolekyuli yeswekile. Ii-Anthocyanidins ziifom ze-aglycone ze-anthocyanins, oko kuthetha ukuba ziyinxalenye engeyiyo iswekile yemolekyuli. Ngokwahlukileyo koko, ii-proanthocyanidins ziipolymers ze-flavan-3-ols, ezakhiwe ziiyunithi ze-catechin kunye ne-epicatechin ezidityaniswe kunye. Lo mahluko wesakhiwo unegalelo kwiiyantlukwano kwiimpawu zazo zomzimba nezekhemikhali, kunye nemisebenzi yazo yebhayoloji.

Omnye umahluko obalulekileyo phakathi kwee-anthocyanins kunye nee-proanthocyanidins kukuzinza kwazo kunye nokufumaneka kwazo. Ii-Anthocyanins ziikhompawundi ezingazinzanga ezinokonakala ngokulula zizinto ezifana nobushushu, ukukhanya, kunye notshintsho lwe-pH. Oku kunokuchaphazela ukufumaneka kwazo kunye neenzuzo ezinokubakho kwimpilo. Kwelinye icala, ii-proanthocyanidins zizinzile ngakumbi kwaye ziyamelana nokuwohloka, nto leyo enokuba negalelo kwi-bioavailability yazo ephezulu kunye nomsebenzi webhayoloji emzimbeni.

Ngokuphathelele iingenelo zempilo, zombini ii-anthocyanins kunye nee-proanthocyanidins ziye zafundwa ngenxa yendima yazo enokubakho ekuthinteleni izifo ezingapheliyo kunye nokukhuthaza impilo iyonke. Ii-anthocyanins ziye zanxulunyaniswa nemiphumo yokulwa nokudumba, umhlaza, kunye nokukhusela imithambo-luvo, kunye neengenelo zentliziyo ezifana nokuphucula ukusebenza kwemithambo yegazi kunye nokunciphisa umngcipheko we-atherosclerosis. Ii-proanthocyanidins ziye zaphandwa ngenxa yeempawu zazo zokulwa ne-antioxidant, ukulwa nokudumba, kunye nokulwa neentsholongwane, kunye nokukwazi kwazo ukuxhasa impilo yentliziyo, ukuphucula ukuqina kolusu, kunye nokukhusela ekunciphiseni kwengqondo okunxulumene nobudala.

Kubalulekile ukuqaphela ukuba iziphumo zempilo ze-anthocyanins kunye ne-proanthocyanidins zisaphandwa ngokukhutheleyo, kwaye kufuneka uphando olongezelelekileyo ukuze kuqondwe ngokupheleleyo iindlela zokusebenza kwazo kunye nokusetyenziswa kwazo okunokwenzeka konyango. Ukongeza, ukufumaneka kwezinto eziphilayo kunye ne-metabolism yezi zinto emzimbeni womntu kunokwahluka ngokuxhomekeke kwizinto ezifana nomahluko womntu ngamnye, i-matrix yokutya, kunye neendlela zokucubungula.

Ukuqukumbela, ii-anthocyanins kunye nee-proanthocyanidins ziindidi ezimbini zeekhompawundi zezityalo ezibonelela ngeenzuzo ezahlukeneyo zempilo ngenxa yeempawu zazo ze-antioxidant kunye ne-bioactive. Nangona zabelana ngokufana okuthile ngokwemiphumo yazo ye-antioxidant kunye neenzuzo zempilo ezinokubakho, zikwanomahluko owahlukileyo kwisakhiwo sazo seekhemikhali, imithombo, uzinzo, kunye nokufumaneka kwazo. Ukuqonda iimpawu ezizodwa zezi khompawundi kunokusinceda siqonde iindima zazo ezahlukeneyo ekukhuthazeni impilo kunye nokuthintela izifo.
