Pinobanksin
Encyclopedia
Pinobanksin is an antioxidant
bioflavonoid
(specifically a dihydroflavonol, a category of flavonol) that inhibits peroxidation
of low density lipoprotein
and it has electron donor properties reducing alpha-tocopherol
radicals. It is present in sunflower
honey
.
Pinobanksin can be obtained from pinocembrin
.
Antioxidant
An antioxidant is a molecule capable of inhibiting the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons or hydrogen from a substance to an oxidizing agent. Oxidation reactions can produce free radicals. In turn, these radicals can start chain reactions. When...

Lipid peroxidation
Lipid peroxidation refers to the oxidative degradation of lipids. It is the process in which free radicals "steal" electrons from the lipids in cell membranes, resulting in cell damage. This process proceeds by a free radical chain reaction mechanism...
