Vitamin E hainhuwi uye isinganakidze mwenje yero mafuta soluble vhitamini ine antioxidant, anticancer, anti-kuzvimba uye mamwe mabasa. Zvinoenderana nemaitiro ayo mamorekuru, anogona kukamurwa kuita mapoka maviri: tocopherols uye tocotrienols. Chikamu chega chega chakakamurwa kuita mhando ina zvichienderana nenzvimbo yemethyl pane chromophore mhete: alpha, beta, gamma, uye delta [1-2]. Mishonga ine hukama ne tocopherols, senge tocotrienols, ine chimwe chiitiko kana zvinotsiva zvakasiyana, asi basa re tocopherols rakaderedzwa zvakanyanya.

Ose ari maviri tocopherol uye tocotrienol ane yakasimba antioxidant mhedzisiro. Nekuda kwekuita kwe alpha tocopherol transfer protein (alpha TP) uye tocopherol binding protein (TBP) mumuviri, tocopherol inobatwa nyore nyore uye kushandiswa nemuviri. Naizvozvo, alpha tocopherol inoonekwa seyakanyanya kuratidzwa kwevhitamini E's antioxidant basa mumuviri. Alpha tocopherol, ine molecular formula yeC29H50O2 uye molecular huremu hwe430.5, yakakamurwa kuva marudzi maviri zvichienderana nekwakabva: yakasikwa uye yakagadzirwa, inoratidzwa seD-mhando uye L-mhando, zvichiteerana. Natural alpha tocopherol iri muR conformation (RRR), nepo artificially synthesized alpha tocopherol iri muRS conformation (RRR, RSR, RRS, RSS, SRR, SSR, SRS, SSS). Iko kuwirirana kune hukama nebasa rayo, uye zvidzidzo zvakawana kuti alpha tocopherol chete ine 2R kana kupfuura inogona kushandiswa uye kubatwa nemuviri. Naizvozvo, yakasikwa alpha tocopherol ine hutano hwepamusoro uye yakachengeteka kupfuura yakagadzirwa alpha tocopherol.
