Palmer said Replere is the first antioxidant skin care line that targets the five free radicals that damage and age the skin: peroxyl
, hydroxyl, peroxynitrite, superoxide anion and singlet oxygen.
We observed that the chemoluminescence induced by the peroxyl
radical generation, initiated by AAPH in the ORAC assay, decreased following addition of lichen extracts; ORAC values were 0.
Several adverse health effects, due to the presence of free reactive oxygen species (ROS), such as superoxide radical, hydroxyl radical, peroxyl
radical, during lipid oxidation, have been reported (Nissen et al.
As one of the highest-ORAC berries and fruits found in nature, maqui has been shown to quench five free radicals known to cause damage: hyroxyl, peroxyl
, peroxynitrite, singlet oxygen and superoxide anion, as shown through the Total ORAC Test.
Induction of DNA damage by dimethylarsenic, a metabolite of inorganic arsenics, is for the major part likely due to its peroxyl
Specific polyphenols are able to reduce free-radicals formation, to scavenge free radicals, particularly, superoxide and hydroxyl radicals, to reduce lipid peroxyl
radicals and to inhibit lipid peroxidation .
They used peroxyl
radical and oxygen-sensitive fluorescent dyes, encapsulated in the lipid phase of colloidal particles, to measure the relative susceptibility of the encapsulated material to react with free radicals generated in the aqueous phase and oxygen from the ambient environment.
radicals and hydroxyl radical are the main ROS.
As an antioxidant, vitamin E scavenges peroxyl
radicals and quenches other free radicals such as singlet [0.
Reduction of peroxyl
, ascorbyl and chromanoxyl radicals.
releases into the organism 5,100 ORAC units of antioxidant power specifically against Peroxyl
Radicals (ROO) the most abundant free radical in the human body; plus 17,800 ORAC units of antioxidant power combined against the other four predominant Reactive Oxidant Species (ROS) in the body, Hydroxyl Radicals, Superoxide Anion Radicals, Peroxynitrite and Singlet Oxygen; plus 75% of Natural Total Polyphenols including the highly valued Anthocyanins and Delphinidins components.
Uric acid is a metabolite that can function in the plasma as an antioxidant due to its capacity to neutralise the peroxyl
