dehydroasorbic acid is the reduced form of ascorbic acid I am wondering if you can make dehydroascorbic acid in your kitchen by starting out with ascorbic acid and adding a reducing agent? Any ideas?
wiki page on this substance ttp://en.wikipedia.org/wiki/Dehydroascorbic_acid you must add an H to the beginning of that link
is it possible that mixing glutathione and ascorbic acid together might generate dehydroascorbic acid?
found a reference that you can create dehydroascorbic acid by adding something called norit to ascorbic acid ww.sciencelab.com/page/S/PVAR/23014/SLC3553
actually, a "drug" is defined as something man-made. Vitamin C, calcium citrate, vitamin D etc. are not drugs because they occur in nature and naturally in our foods and in our bodies same is true for dehydroascorbic acid (DA), it is found in all foods that are naturally high in vitamin C and it is an important nutrient in the body. It is the only form of vitamin C that crosses the blood brain barrier, and the only form that penetrates deep into the mitochondria of the cell You can do a Google search and you can see that scientists have used it to help people recover from strokes etc. You can buy online. It only costs about $140 per 5 g. Consider that a daily dose might be 3 to 5 g, well you do the math on that So I was thinking of making it. Doesn't seem like it would be too hard. But as usual I don't get any help on these freaking boards and I don't even know why I bother posting because nobody ever seems to actually give me the information I need Oh well
My advice in good faith is do not try to produce it in your kitchen and to eat it. Try to eat foods that contain this product.
yes that's about what I expected That's pretty much the answer I always get on these boards. Nobody really helps you out they just advise you to not do anything
I just figured it out. You just add iodine to a water-based mixture of vitamin C Voila! You have dehydroascorbic acid You don't think this will kill me do you? Make me grow a third arm? Make me grow elf ears? LOL! Seriously, why are you geeks on these boards so unhelpful?
I do not know if you're aware of what you say. With iodine determine the amount of vitamin C in one product. Take care not to make vinegar. ....................................................................................Wikipedia:Iodine Catalysis Or maybe something methamphetamine. ....................................................................................Wikipedia/Iodine clandestine use
are you people really that stupid? You think that by combining vitamin C and iodine you can make methamphetamine? Seriously? This might explain why I never get any help on boards like this. It's populated by morons who fully and completely believe they are intelligent here's a little bit of light reading for all of you geniuses here ww.outreach.canterbury.ac.nz/chemistry/vitamin_C_iodine.shtml This method determines the vitamin C concentration in a solution by a redox titration using iodine. Vitamin C, more properly called ascorbic acid, is an essential antioxidant needed by the human body (see additional notes). As the iodine is added during the titration, the ascorbic acid is oxidised to dehydroascorbic acid, while the iodine is reduced to iodide ions. ascorbic acid + I2 --> 2 I- + dehydroascorbic acid
by the way I just combined some vitamin C and Lugols solution in a glass of water Drank it down! Yummy! Methamphetamines for breakfast! LOL!
By this defintion, Aspirin and ACE inhinbitors aren't drugs either, neither is penicillin, Opium, Coccaine, or THC.
Isn't it the other way around? Dehydroascobric acid is the OXIDIZED form of ascorbic acid. Thus, you can make dehydroascorbic acid from ascorbic acid by adding an oxidizing agent. Yes, elemental iodine (the brown type) works. However, I have to wonder. Why are you intent on ingesting dehydroascorbic acid? It's ascorbic acid that has nutritional properties, not dehydroascorbic acid. Your body converts ascorbic acid to dehydroascorbic acid when it uses ascorbic acid to replenish your body's natural antioxidants. There's also a way to make dehydroascorbic acid from ascorbic via dichloroindophenol (NOTE: it's an analytical technique. Not meant to be ingested). You need dichloroindophenol, oxalic acid (read: toxic) and I don't remember the third reagent.
Maybe try ReCverin? Lapis_x: I have been using a product called ReCverin 50/50 the last few weeks. It is a vitamin C skin serum that has a lot of dehydroascorbic acid in it. I like to use it on my face and on my lips, so I get it in my mouth sometimes. Based on the ingredients, I can't think of any reason why a person couldn't eat it if they wanted to...and it actually tastes very good! The website recverin.com is very informative about dehydroascorbic, and there is a real interesting discussion about zucchini...I think you might discover that you can get this form of vitamin C in your diet in natural foods without eating toxic chemicals. I understand your frustration with forums when you post and don't immediately get good replies. But others are looking at the thread, and someone with just the info you seek might be intimidated and reluctant to post if you are making caustic comments. For that reason alone, if not common courtesy, I think you should try to be more civil on these forums. I posted this because I share your enthusiasm for dehydroascorbic acid, and I'm concerned about you eating excessive iodine. I hope this info is helpful to you, but if it isn't, I hope it doesn't prompt one of your nasty replies. Joyce
The problem with any direct oxidation of ascorbic acid is that DHA is actually a stronger reducing agent so this, too, will be oxidised in the process. Otherwise hydrogen peroxide would be a far less harmful candidate that iodine. Here, for your interest, is one synthesis: Eleftheria K. Kolioua and Panayiotis V. Ioannou, a, aDepartment of Chemistry, University of Patras, GRC-26500 Patras, Greece Received 29 September 2004; revised 16 November 2004; accepted 25 November 2004. Available online 18 December 2004. Abstract The catalytic system Cu(AcO)2–pyridine 1:4 mol % in methanol, slowly catalyses the air oxidation of ascorbic acid to the 2-methyl hemi-ketal of dehydroascorbic acid 5, and hydrogen peroxide. However, with Cu(AcO)2–pyridine 3:4 mol % the air oxidation is quite fast and no hydrogen peroxide is present at the end of the reaction. Removal of the catalyst and refluxing the foamy 5 in MeCN gives the oxidized, dimeric, dehydroascorbic acid in very good yields (70%) contaminated by 1–2% MeCN. Of course you certainly don't want nasty stinky pyridine in your kitchen, nor do really want methanol or acetonitrile lying around there either. But you see that the synthesis is not trivial and that is why DHA is rather expensive to buy. So it seems to be either spend up big or just suck lots of oranges and let your body do the partial oxidation for you with its customary efficiency.
Why don't you look it up on wiki? http://en.wikipedia.org/wiki/Dehydroascorbic_acid Please Register or Log in to view the hidden image! Ruhi min wiji, ya hamra. Budrabik kef.
