Alpha-Lipoic
Acid
Alpha-Lipoic Acid, also known as lipoic acid, is a highly
potent antioxidant that counteracts reactive free radicals in
the mitochondria, the power plants of cells where energy for all
cellular activities is generated. Some scientists believe that
mitochondrial free radicals play an important role in human aging,
and have theorized that extra amounts of free-radical inhibiting
compounds such as alpha lipoic acid may be able to slow aging.
Alpha-Lipoic Acid is also effective in recycling other antioxidants
such as Vitamin E back into their original form after they detoxify
free radicals. There also is evidence that alpha lipoic acid can
reduce glycation damage due to excess glucose in the blood, which
may be involved in aging, and that it can improve patients with
diabetes, which has been described as an accelerated form of aging.
Anti oxidant activity of Alpha Lipoic Acid, an anti aging element
Alpha lipoic acid has been recognized as a broad spectrum anti-oxidant
for its ability:
- to act both in cell membranes including nuclear membrane and
interior of the cell
- to regenerate main other antioxidants from their inactive or
radical forms including vitamin C, vitamin E and glutathione.
Since it recharges oxidized vitamins C and E which are exogenous
antioxidants, Alpha Lipoic Acid counterbalance these vitamins
during chronic and transientdeficiency
- to neutralize free radicals through different mechanisms in
different organs (it also passes blood brain barrier)
- to increase the level of glutathione (one of the major endogenous
antioxidants made within the cells) in the cell.
Level of glutathione decreases in all immune compromised conditions
and during stress. Thus it compensate for transient depletions
of glutathione during stress to counteract the deteriorative effects
of chronic hyperglycemia by increasing glucose utilization. Elevated
glucose level triggers free radical reactions to control the AGE
products. AGEs, or advanced glycosylated products may result in
dysfunction of normal proteins and decreased turnover and tissue
remodeling
Metabolic activity of Alpha Lipoic Acid
Alpha Lipoic Acid also serves as a cofactor for a number of vital
enzymes responsible for the conversion of glucose, fatty acids
and other energy sources into chemical energy (ATP). Small amount
of Alpha Lipoic Acid are bound chemically (coenzyme) at the active
site of enzyme complexes, Alpha Lipoic Acid works by becoming
reduced and facilitates biological reactions from which energy
is harnessed.
