+'''ビタミン'''とは、[[Organic compound/ja|有機分子]]（または[[vitamer/ja|ビタマー]]と呼ばれる密接に関連した分子の集合）であり、適切な[[metabolism/ja|代謝]]機能のために少量であれば[[organism/ja|生物]]にとって[[Nutrient/ja#Essential nutrients|必須]]である。必須栄養素は、生存に十分な量を生体内で[[biosynthesis/ja|合成]]することができないため、[[Diet (nutrition)/ja|食事]]によって摂取しなければならない。例えば、[[vitamin C/ja|ビタミンC]]はある種では合成できるが、他の種では合成できない。 ほとんどのビタミンは単一分子ではなく、ビタマーと呼ばれる関連分子のグループである。例えば、[[vitamin E/ja|ビタミンE]]には8つのビタマーがある：4つの[[tocopherol/ja|トコフェロール]]と4つの[[tocotrienol/ja|トコトリエノール]]である。
