From
Cell to Super Cell - with Glutathione

Imagine
you're a cell.
Inside
your body runs the machinery that creates life itself. But as that
machinery keeps running, day after day, you begin to get worn out
- the friction and the processes that cause damage (here the "free-radicals"
- highly destructive little entities generated by biochemical processes,
as well as pollutants, UV radiation and other sources) start to create
havoc and you begin to lose the battle to disease, old age and ultimately
death.
In
fact your battle would be over much sooner were it not for the numerous
mechanisms that you and other mammalian cells evolved over millions
of years, as protection from the injury that can result from your
normal functional processes. The foremost among these internal protective
systems is the "Glutathione antioxidant system."
Glutathione,
a small molecule composed of three amino acids - glycine, glutamate
and cysteine - acts as your cellular Super-Mop, soaking up "free-radicals"
(with the help of the sulfur-containing portion of the cysteine molecule),
protecting your cellular membranes and internal organs from the cascading
destruction they can cause.
Besides
being the major antioxidant that you produce as protection from "free-radicals,"
glutathione is also a very important detoxifying agent, enabling you
to get rid of undesirable toxins and pollutants. If you were a liver,
kidney or lung cell, you would contain high levels of glutathione,
as you'd be exposed to the greatest levels of toxins.
Glutathione
also helps you dispose of many cancer- producing chemicals, heavy
metals, drug metabolites etc. that invade the pristine recesses of
your cellular world. And Mother Nature (the first recycler) also designed
you to use glutathione to recycle other well-known antioxidants such
as vitamin C and vitamin E, keeping them in their active state.
If
you were a cell delegated to the immune system department, you would
require glutathione for many of the intricate steps needed to carry
out your essential immune response functions - such as multiplying
to make many clones of yourself, to mount a full-bodied immune response,
or "neutralizing" undesirable elements of the cellular community,
like cancerous or virally infected cells.
But
your finicky cell membrane does not allow whole glutathione molecules
to cross over directly into your cellular spaces. And every time a
molecule of glutathione neutralizes a destructive free-radical or
toxin, it fatally binds with the undesirable element and is washed
out with them in the bile or the urine.
So
how do you replenish your stores and get your daily fix of glutathione?
Simple. You manufacture it in your cellular factory, from its raw
materials - glycine, glutamate and cysteine.
If
your human eats a diet high in fresh fruits and vegetables and freshly
prepared meats, you should get be getting enough glutamate and glycine.
But cystine comes mostly from eggs, milk and cheese. And when eggs,
milk and cheese are cooked or processed, the composition of Cystine
is changed to Cysteine (small difference in spelling, but BIG difference
in action). While still a valuable protein, it can no longer feed
your glutathione levels.
If
you can get a sufficient supply of cysteine (which determines the
rate at which you can make glutathione), your arsenal is well- stocked.
If not, you and your human are at a strategic disadvantage in the
battle of "Cell v/s Free-radical Destroyers."
As
a normal, healthy cell, increasing your glutathione levels could help
you and your human maintain that strategic advantage in the battle
against free-radicals. If you're not really in your prime, boosting
your levels could tip the scales in your favor, and help you fight
the cellular damage that causes disease and aging.
