Some antioxidants are only found in a few organisms, and can be pathogens or virulence factors. [61] The interactions between these different antioxidants may be synergistic and interdependent. [62] [63] The action of one antioxidant may therefore depend on the proper function of other members of the antioxidant system. [43]
Glutathione (GSH, / ˌ ɡ l uː t ə ˈ θ aɪ oʊ n /) is an organic compound with the chemical formula HOCOCH(NH 2)CH 2 CH 2 CONHCH(CH 2 SH)CONHCH 2 COOH.It is an antioxidant in plants, animals, fungi, and some bacteria and archaea.
This is a list of antioxidants naturally occurring in food. Vitamin C and vitamin E – which are ubiquitous among raw plant foods – are confirmed as dietary antioxidants, whereas vitamin A becomes an antioxidant following metabolism of provitamin A beta-carotene and cryptoxanthin .

Coenzyme Q 10 (CoQ 10 / ˌ k oʊ k j uː ˈ t ɛ n /), also known as ubiquinone, is a naturally occurring biochemical cofactor (coenzyme) and an antioxidant produced by the human body. [1] [2] [3] It can also be obtained from dietary sources, such as meat, fish, seed oils, vegetables, and dietary supplements.
The tocopherols function as fat-soluble antioxidants which may help protect cell membranes from reactive oxygen species. Vitamin E is classified as an essential nutrient for humans. [ 1 ] [ 2 ] [ 3 ] Various government organizations recommend that adults consume between 3 and 15 mg per day, while a 2016 worldwide review reported a median ...
Catechin / ˈ k æ t ɪ k ɪ n / is a flavan-3-ol, a type of secondary metabolite providing antioxidant roles in plants. It belongs to the subgroup of polyphenols called flavonoids. The name of the catechin chemical family derives from catechu, which is the tannic juice or boiled extract of Mimosa catechu (Acacia catechu L.f). [1]
Although anthocyanins have been shown to have antioxidant properties in vitro, [49] there is no evidence for antioxidant effects in humans after consuming foods rich in anthocyanins. [ 5 ] [ 50 ] [ 51 ] Unlike controlled test-tube conditions, the fate of anthocyanins in vivo shows they are poorly conserved (less than 5%), with most of what is ...
