In another study pertaining to the conversion of Xanthohumol, a prenylated chalconoid, which has antioxidant and anticancer properties, Aspergillus ochraceus was found to be able to convert it into a stronger antioxidant, increasing the compounds radical scavenging properties. [28]
Free radicals can oxidize LDL, and this is a key event in the formation of plaque in arteries, leading to heart disease and stroke. [23] These are examples of how the free-radical theory of aging has been used to neatly "explain" the origin of many chronic diseases. [24]
[10] [13] [14] Upon the exposure to light, the aroma 3-methyl-2,4-nonanedione (MND) is formed from furan fatty acids in the reaction with singlet oxygen, which has a hay-like odor and is found, for example, in green tea. [15] [16] Furan fatty acids act as radical scavengers. In the example, two hydroxyl radicals are trapped to form a dioxoenoic ...
Oxidative stress mechanisms in tissue injury. Free radical toxicity induced by xenobiotics and the subsequent detoxification by cellular enzymes (termination).. Oxidative stress reflects an imbalance between the systemic manifestation of reactive oxygen species and a biological system's ability to readily detoxify the reactive intermediates or to repair the resulting damage.

The mitochondrial theory of ageing has two varieties: free radical and non-free radical. The first is one of the variants of the free radical theory of ageing. It was formulated by J. Miquel and colleagues in 1980 [1] and was developed in the works of Linnane and coworkers (1989). [2] The second was proposed by A. N. Lobachev in 1978. [3]

Tocopherols function by donating H atoms to radicals (X). Vitamin E may have various roles as a vitamin. [1] Many biological functions have been postulated, including a role as a lipid-soluble antioxidant. [1] In this role, vitamin E acts as a radical scavenger, delivering a hydrogen (H) atom to free radicals.
