heavy water

or a 250 year old complaining that her 35 cent coupon didnt come off on her receipt.

Ok i see how it could extend the age limits, but would it also delay the onset of such things as lack of eyesight, hearing and all the other problems that come with old age?

damn, you mean NOW i gotta wait til i'm like 200 when i get SS check? Geez, I was worried it wouldnt be there when i'm 65.........

New show on Jerry Springer: I'm in love with my great great great GREAT grandma.... HA!

Doesn't the telomeres more or less proove that life on Earth was designed?

has anyone made any heavy water yet?

Ah, way to ressurect old threads...

Yes, heavy water is nothing new.

is their a HO molecule that is in liquid form?

If someone found a way to deplete or alter "telomeres", would that lengthen ones lifespan?

No, but there is a OH- ion that is a very powerful alkali. All other powerful alkali react with water to form OH-, just like all powerful acids react with water to form H3O+.

Dragonrider is right about the telomeres. All telomeres are a large group of TTAGGGTTAGGG... at the end of a chromosome. They protect and stabilize the chromosome ends. In some parts of the body the telomeres do get regenerated. The skin is one example I know of. The cells make a revese transcriptase called telomerase.

oi whats the chemical name for water lol? H2O apart frm 'water' ?

The chemical name for water is H2O (l), with (l) meaning that's in liquid form.

Wrong!!!!! Heavy water is still H2O but all the atoms have extra neutrons making them isotopes and less stable. Sorry Val, I finally got to call you on something!

NOOO i mean is it dihydrogen monoxide or hydrogen hydroxide?

omg cant be dihydrogen monoxide!!

It is colourless, odourless, tasteless and kills uncounted thousands of people each year. It is even present in some imported foods. The chemical is commonly found in pre-cancerous cells and is prevalent in acid rain. In its solid state DHMO causes some tissue damage and in gaseous form severe burns.

You must've read this:

From snopes.com

BAN DIHYDROGEN MONOXIDE!
Dihydrogen monoxide is colorless, odorless, tasteless, and kills uncounted thousands of people every year. Most of these deaths are caused by accidental inhalation of DHMO, but the dangers of dihydrogen monoxide do not end there. Prolonged exposure to its solid form causes severe tissue damage. Symptoms of DHMO ingestion can include excessive sweating and urination, and possibly a bloated feeling, nausea, vomiting and body electrolyte imbalance. For those who have become dependent, DHMO withdrawal means certain death.

Dihydrogen monoxide:


is also known as hydroxl acid, and is the major component of acid rain.
contributes to the "greenhouse effect."
may cause severe burns.
contributes to the erosion of our natural landscape.
accelerates corrosion and rusting of many metals.
may cause electrical failures and decreased effectiveness of automobile brakes.
has been found in excised tumors of terminal cancer patients.
Contamination is reaching epidemic proportions!

Quantities of dihydrogen monoxide have been found in almost every stream, lake, and reservoir in America today. But the pollution is global, and the contaminant has even been found in Antarctic ice. DHMO has caused millions of dollars of property damage in the midwest, and recently California.

Despite the danger, dihydrogen monoxide is often used:


as an industrial solvent and coolant.
in nuclear power plants.
in the production of styrofoam.
as a fire retardant.
in many forms of cruel animal research.
in the distribution of pesticides. Even after washing, produce remains contaminated by this chemical.
as an additive in certain "junk-foods" and other food products.
Companies dump waste DHMO into rivers and the ocean, and nothing can be done to stop them because this practice is still legal. The impact on wildlife is extreme, and we cannot afford to ignore it any longer!

The American government has refused to ban the production, distribution, or use of this damaging chemical due to its "importance to the economic health of this nation." In fact, the navy and other military organizations are conducting experiments with DHMO, and designing multi-billion dollar devices to control and utilize it during warfare situations. Hundreds of military research facilities receive tons of it through a highly sophisticated underground distribution network. Many store large quantities for later use.

Heavy water is water (H2O) in which oxygen is bound to atoms of the hydrogen isotope deuterium (2H). Heavy water is so named because it is significantly more dense (>1.1 g/cm3) than ordinary ("light") water, 1H2O (1 gm/cm3). Heavy water is not radioactive and has the same chemical properties as light water; a person could drink a glass of heavy water without harm. However, heavy water is better than light water at moderating (slowing) neutrons, which makes it useful in some nuclear reactor cores. Its scarcity during World War II, partly assured by bombing raids and daring Allied commando missions to destroy heavy-water production facilities, interfered critically with the German and Japanese nuclear programs.
The effect of isotopic replacement that has particularly attracted the attention of chemists is the kinetic isotope effect (Thomson J. F., 1963). The substitution of deuterium for hydrogen in a chemical bond of macromolecules can markedly affect the rate of scission of this bond, and so exert pronounced effects on the relative rates of chemical reactions going on in heavy water with participation of macromolecules. This change in rate of scission of a bond resulting from the substitution of deuterium for hydrogen is a primary isotopic effect. The direction and magnitude of the isotope effect will depend on the kind of transition state involved in the activated reaction complex, but in general, deuterium depresses reaction rates. The usual terminology of the chemist to describe the primary kinetic effect is in terms of the ratio of the specific rate constants kh/kd. The maximum positive primary kinetic isotopic effect which can be expected at ordinary temperatures in a chemical reaction leading to rupture of bonds involving hydrogen can be readily calculated, and the maximum ratio kh/kd in macromolecules is in the range of 7 to 10 for C-H versus C-2H, N-H versus N-2H, and O-H versus O-2H bonds. However, maximum ratios are seldom observed for a variety of reasons, but values of kh/kd in the range of 2 to 5 are common (Wiberg K. B., 1955). Deuterium located at positions in a macromolecule other than at the reaction locus can also affect the rate of a reaction. Such an effect is a secondary isotope effect and is usually much smaller than a primary isotope effect.
When the macromolecules transfer to deuterated medium not only water due to the reaction of an exchange (protonated water- heavy water) dilutes with deuterium, but also occurs a very fast isotopic (1Н-2Н)-exchange in hydroxylic (-OH), carboxilic (-COOH), sulfurhydrilic (-SH) and nitrogen (-NH; -NH2) groups of all organic compounds including the nucleic acids and proteins. It is known, that in these conditions only С-2Н bond is not exposed to isotopic exchange and thereof only the species of macromolecules with С-2H type of bonds can be synthesized de novo. This is very probably, that the most effects, observed at adaptation to heavy water are connected with the formation in heavy water molecules with conformations having the other structural and dynamic properties, than conformations, formed with participation of hydrogen, and consequently having other activity and biophysical properties. According to the theory of absolute speeds the break of С-H-bonds can occur faster, than С-D-bonds, mobility of an deuterium ion is less, than mobility of protium ion, the constant of ionization heavy water is a little bit less than ionization constant of heavy water. So it would be much easy to obtain energy from heavy water than from ordinary water. Thus, in principle, the structures of macromolecules may to be more friable that those are forming in ordinary heavy water.

Alot of this is new to me, and I might have missed this in my speed-reading, but

Is there any heavy water in our bodies? What's the natural sources for this 'heavy water'?

hmm not up to now.. today we call cells with such altered telomers cancer
.. they life long and are very tough (but dont form organs and other usefull parts)

heavy water is one of the ingredients you need to make a nuclear bomb, hitler only needed a couple more barrels of this and he would have had a nuke before us, and the world would be much different today if we didnt destroy his heavy water.
