The metabolomics analyses further reveal that the mutants accumulate higher amounts of α-and γ-tocopherols, which are important antioxidants for protection against oxidative damage. (frontiersin.org)

Inhibit1
Antioxidants are compounds that inhibit oxidation (usually occurring as autoxidation), a chemical reaction that can produce free radicals. (wikipedia.org)
Preservatives1
Antioxidants are an especially important class of preservatives as, unlike bacterial or fungal spoilage, oxidation reactions still occur relatively rapidly in frozen or refrigerated food. (wikipedia.org)
Free radical2
Clinically, in a disease ameliorated by ascorbate, there is a suppression of symptoms only with very high doses and approximately to that extent which a nonrate-limited,_antioxidant_free_radical_scavenger, might be expected to affect that disease process if all harmful free radicals and highly reactive oxidizing substances were quenched. (mall-net.com)
In most pathologic processes, the rate at which free radicals and highly reactive oxidants are produced, exceeds the rate at which the ordinary rate-limited antioxidant free radical scavenging mechanisms can quench those free radicals and oxidants. (mall-net.com)
Biochemistry1
However, it was the identification of vitamins C and E as antioxidants that revolutionized the field and led to the realization of the importance of antioxidants in the biochemistry of living organisms. (wikipedia.org)
Oxygen5
The evolution of angiosperm plants between 50 and 200 million years ago resulted in the development of many antioxidant pigments - particularly during the Jurassic period - as chemical defences against reactive oxygen species that are byproducts of photosynthesis. (wikipedia.org)
Originally, the term antioxidant specifically referred to a chemical that prevented the consumption of oxygen. (wikipedia.org)
Antioxidant activity could be measured simply by placing the fat in a closed container with oxygen and measuring the rate of oxygen consumption. (wikipedia.org)
Exposure to oxygen and sunlight are the two main factors in the oxidation of food, so food is preserved by keeping in the dark and sealing it in containers or even coating it in wax, as with cucumbers. (wikipedia.org)
H2O2 increases germination rates by breaking down the seed coat, thus allowing the seed to take in oxygen more quickly. (researchgate.net)

Effect2
Low or moderate doses (doses substantially below bowel tolerance) usually had no noticeable immediate beneficial effects, but high doses (doses just below the amount that would produce diarrhea in a patient tolerant to ascorbate) would have the effect of markedly suppressing symptoms as the high dose levels were reached. (mall-net.com)
The enhanced effects on germination with H2O2 have a) been reported for seed with pathogenic infestations (Szopniska, 2014) i.e. a biocidal effect, and b) mediated through the oxidation of germination inhibitors present in the seed coat or/and in the pericarp, i.e. a seed treatment effect. (researchgate.net)
High3
but if the ascorbate/dehydroascorbate (AA/DHA) ratio is kept high (the redox potential kept reducing) until the unstable dehydro- ascorbate undergoes hydrolysis or can be reduced back to ascorbate, the dehydroascorbate will do no harm. (mall-net.com)
Since even at very high doses, ascorbate is virtually nontoxic, it may be given in the enormous doses necessary to quench almost all unwanted free radicals and oxidants. (mall-net.com)
It is as if a threshold were reached at which point the ascorbate becomes very effective. (mall-net.com)
