2,4,6-TTBP is used as stabilizers, free-radical scavengers and antioxidants in technical applications, such as in fuels, hydraulic fluids and lubricating oils, as well as in elastomeric and thermoplastic polymers.
As part of their adaptation from marine life, terrestrial plants began producing non-marine antioxidants such as ascorbic acid (), polyphenols, and tocopherols.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 ...
Myricetin's pro-oxidative capabilities can also be seen in its ability to act as an inhibitory agent against glutathione reductase, which is responsible for regenerating glutathione, a scavenger of free radicals and peroxides. [1]
In atmospheric chemistry, the most common scavenger is the hydroxyl radical, a short-lived radical produced photolytically in the atmosphere. It is the most important oxidant for carbon monoxide, methane and other hydrocarbons, sulfur dioxide, hydrogen sulfide, and most of other contaminants, removing them from the atmosphere.
In this role, vitamin E acts as a radical scavenger, delivering a hydrogen (H) atom to free radicals. At 323 kJ/mol, the O-H bond in tocopherols is about 10% weaker than in most other phenols. [23] This weak bond allows the vitamin to donate a hydrogen atom to the peroxyl radical and other free radicals, minimizing
Furan fatty acids are very effectively acting as radical scavengers. In this process dioxoenoic fatty acids are formed, which are by themselves very unstable and form thioethers with thiols such as cysteine or glutathione. [17] As potent antioxidants, they specifically trap hydroxyl radicals. [18]
Tocopherols are radical scavengers, delivering an H atom to quench free radicals. At 323 kJ/mol, the O–H bond in tocopherols is approximately 10% weaker than in most other phenols. [14] This weak bond allows the vitamin to donate a hydrogen atom to the peroxyl radical and other free radicals, minimizing their
