Vitamin E yɛ asɛmfua a wɔbom yɛ ma nnuru 8 a ɛfa ho a ɛyɛ tocopherol ne tocotrienol. Wɔyɛ srade kuw bi- vitamin ahorow a ɛyɛ mmerɛw a ɛwɔ antioxidant dwumadi. Wɔ saa nnuru yi mu no, esiane sɛ onipa nipadua no pɛ sɛ ɛtwe -tocopherol nti, -Tocopherol na ɛwɔ bioavailability kɛse na wɔayɛ ho nhwehwɛmu kɛse.
Wɔkyerɛ sɛ alpha-Tocopherol ne srade a ɛho hia sen biara-aduru a ɛko tia ɔyare mmoawa. Ɛsɛe free radical intermediates na esiw free radicals nkɔnsɔnkɔnsɔn nyin ano, na ɛnam so bɔ nkwammoaa no mu ntini no ho ban fi lipid peroxides a ɛnam peroxidation chain reaction no so sɛe no ho. oxidation tebea a ɛba -tocopherol free radicals betumi ayɛ antioxidants afoforo te sɛ vitamin C, retinol anaa panthenol so tew ma ɛsan kɔ tebea a wɔatew so a ɛyɛ nnam no mu na ɛkɔ so di dwuma a ɛko tia ɔyare mmoawa.
