Amavithamini ayizimboni ezikhethekile eziphilayo, zonke zazo ziyi-molecular ephansi futhi zisebenza ngokwezinto eziphilayo, zinezakhi ezahlukene zamakhemikhali. Ukuba izingxenye ze-enzyme, zithatha ingxenye esebenzayo kuzo zonke izinqubo zokuguqula umzimba nokuguqulwa kwamandla. Udokotela waseRussia M. Lunin wayengowokuqala ukufunda ngokubaluleka okukhulu kwempilo yabantu.
Okwamanje, kunezivithamini ezingaba ngu-30, konke okuye kwacutshungulwa kakhulu ososayensi. Kulezi zakhi ezingamashumi amathathu, ezingamashumi amabili zibaluleke kakhulu empilweni yabantu, zisiza umzimba ukuba usebenze kahle, uqinisekise ukuthi kuqhutshwa inkambo evamile yezinqubo zokuphila kanye nezidakamizwa.
Izimiso zokuhlelwa kwamavithamini
Amakhemikhali e-Organic afana namavithamini ayimfuneko ebalulekile yokudla, kodwa ekhona ekudleni ngesamba esincane, uma eqhathaniswa nezinsimbi zawo eziyisisekelo. Umzimba wethu ungakwazi ukuhlanganisa kuphela ingxenye encane yalezi zakhi, futhi ngisho nangokwanele okwanele.
Kuze kube manje, ukuhlukaniswa kwamavithamini kusekelwe ikakhulu kwimigomo yemvelaphi yabo yezinto eziphilayo noma zamakhemikhali. Kodwa-ke, ososayensi abaningi bakholelwa ukuthi isimiso esinjalo seyisikhathi eside siphelelwe yisikhathi, ngoba asibonakali izimfanelo zamakhemikhali noma eziphilayo zamaqembu.
I-widely used today is the classification of vitamins for solubility emanzini namafutha. Amavithamini anganelisekile amanzi akwazi ukubuthelwa emzimbeni, "aphile" kuphela egazini. Ukuqhathaniswa nabo akubangeli ukulimala, kepha kumane kukhishwe ngendlela yemvelo, ngomchamo. Amavithamini aqothula emafutheni angakwazi ukubuthelela emathisini e-isibindi namafutha. Ukusebenzisa kwabo ngokweqile kuyingozi, ngoba la mavithamini ayinobuthi emalini ephakeme kakhulu kunejwayelekile.
Ukuhlukaniswa kwamavithamini nge-solubility kubonakala etafuleni elingezansi:
Kunesinye isigaba samavithamini esebenzayo. Itafula lalo hlobo lokuhlukanisa libukeka kanje:
Ukuhlala umuntu onempilo, akudingekile ukutadisha ukuhlukaniswa kwamavithamini. Kubaluleke nakakhulu ukunakekelwa kokudla kokudla kwakho nokutholakala kokudla okunempilo etafuleni lakho.
