General Science / How is vitamin C concentration measured?
« on: 16/09/2010 06:16:46 »All I can think of is the acetic acid is acting as a buffer for the vitamin C, they have similar pKa values.

1. On recorded history from the sea about scurvy incidence, there is no rational ground to accept theory about cause and prevention of the scurvy
2. There is no rational ground to accept theory about cause and prevention of the scurvy based on Lind’s trial.
3. There is no rational ground to accept theory that guinea pig is not able to synthesize the vitamin C.
I presented strong evidence that support my theory. On the other side on this topic no one present any evidence that contradict to my theory.
BTW did you know that Ascorbic acid in cerebral spinal fluid is 3-4 times more concentrated than in peripheral blood (plasma)?
This cofactor should really do something important in our brain, to be 'pumped' so efficiently across the blood brain barrier! []
I start this topic with intention to explain that events that lead to establish the role between vitamin C and scurvy is “The Scurvy, the Vitamin C and the blasphemy” are littered with quackery and need to be re-examined.
Does anybody know what is concentrated ascorbic acid doing in our brains?
Even more concentrated in preterm babies and newborns?
It is an old finding, still a mystery to me!
Linus Pauling and vitamin C(The physical damage to people he (Linus Pauling) led astray cannot be measured.)
QuoteA flyer distributed in 1991 by the Linus Pauling Institute recommended daily doses of 6,000 to 18,000 mg of vitamin C, 400 to 1,600 IU of vitamin E, and 25,000 IU of vitamin A, plus various other vitamins and minerals. These dosages have no proven benefit and can cause troublesome side effects.
The fear from illnesses, diseases and premature death make humans highly vulnerable to quackery. Before any discussion about miracle healing property of vitamin C it is useful to confront with some fact about recently claims about healing property of vitamin C.
...Some ICU operators started giving i.v. vitamin C to severely burned patients.
This recent experimental (poor sheep!) report actually supports previous clinical 'evidence':
Subclinical scurvy should be low AA levels and no signs or symptoms.
Assuming that red gums in a particular area could come much before
and last for long, if the diet is just poor of vitamin C...
Well...there is so much to be studied and confirmed still!
they probably had 'knocked out' the enzyme gene
involved in ascorbate synthesis. This information
probably is in the full-text version which I cannot
reach.
are there simple signs of a
subclinical scurvy, available
in everyday clinical practice?
What could we expect in a child who had been eating for several weeks only pasta/chips and no fruit and veggies?
Mitochondria stop producing enough energy from sugar(vit.B1 deficiency), it's like having
A quick injection of thiamine* and little ascorbic acid by mouth. Easy and cheap.
In this post I pointed out on two facts;
One fact is that treating scurvy on the land was always successful and that on the ship scurvy was nearly impossible to treat.
Second fact is that only crew was vulnerable to scurvy and that officer’s wasn’t.
