Alpha-lipoic Acid––the "Ideal Antioxidant"
The antioxidant potential of a substance is based on a number of criteria, including:
1) Ability to quench specific free-radicals.
2) Ability to bind or "chelate" metal ions that can generate free radicals.
3) Supports function of other antioxidants.
4) Absorption/bioavailability.
5) Concentration in tissues, cells and extra cellular fluids.
6) Ability to function as an antioxidant in fatty and watery environments.
The "ideal antioxidant" would meet all the above criteria. Very few antioxidants do, yet a particular antioxidant with but a few of the characteristics is still valuable and effective. Vitamin E, for example, is one of the most important dietary antioxidants, yet it only works in fatty environments such as cell membranes.
As a team, ALA and DHLA come close to the ideal, for the following reasons:1,2,3
1) ALA is easily absorbed when consumed orally.
2) ALA is readily converted to DHLA in various tissues.
3) As a pair, ALA and DHLA neutralize superoxide, hydroxyl, peroxyl, and hypochlorus radicals.
4) ALA and DHLA form stable complexes with metal ions such as iron, manganese, copper and zinc ions.
5) ALA and DHLA scavenge free radicals in fatty environments and watery environments.
6) DHLA recycles other important antioxidants.
DHLA-regenerates vitamin C, vitamin E and glutathione
Within the cell, antioxidants work as a team to keep free radicals from damaging cell structures. In order to neutralize a free radical, an antioxidant such as vitamin C must give up an electron, which mean it becomes oxidized. Before it can function as an antioxidant once again, it must be regenerated back to its "reduced" form, by gaining an electron to replace the donated electron. For this, ...
