The water boom
Water, The chemistry of life.
Whenever we
attempt to determine whether there is life as we know it on Mars or
other planets, scientists first seek to establish whether or not water
is present. Why? Because life on earth totally depends on water.
A High
percentage of living things, both plant and animal are found in water.
All life on earth is thought to have arisen from water. The bodies of
all living organisms are composed largely of water. About 70 to 90
percent of all organic matter is water.
The chemical
reactions in all plants and animals that support life take place in a
water medium
.
Water not only provides the medium to make these life sustaining
reactions possible, but water itself is often an important reactant or
product of these reactions. In short, the chemistry of life is water
chemistry.
Water, the universal solvent
Water is a
universal, superb solvent due to the marked polarity of the water
molecule and its tendency to form hydrogen bonds with other molecules.
One water molecule, expressed with the chemical symbol H2O,
consists of 2 hydrogen atoms and 1 oxygen atom.
Standing
alone, the hydrogen atom contains one positive proton at its core with
one negative electron revolving around it in a three-dimensional shell.
Oxygen, on the other hand, contains 8 protons in its nucleus with 8
electrons revolving around it. This is often shown in chemical notation
as the letter O surrounded by eight dots representing 4 sets of paired
electrons.
The single
hydrogen electron and the 8 electrons of oxygen are the key to the
chemistry of life because this is where hydrogen and oxygen atoms
combine to form a water molecule, or split to form ions.
Hydrogen
tends to ionize by losing its single electron and form single H+ ions,
which are simply isolated protons since the hydrogen atom contains no
neutrons. A hydrogen bond occurs when the electron of a single hydrogen
atom is shared with another electronegative atom such as oxygen that
lacks an electron.
Polarity of water molecules
In a water
molecule, two hydrogen atoms are covalently bonded to the oxygen atom.
But because the oxygen atom is larger than the hydrogen's, its
attraction for the hydrogen's electrons is correspondingly greater so
the electrons are drawn closer into the shell of the larger oxygen atom
and away from the hydrogen shells. This means that although the water
molecule as a whole is stable, the greater mass of the oxygen nucleus
tends to draw in all the electrons in the molecule including the shared
hydrogen electrons giving the oxygen portion of the molecule a slight
electronegative charge.
The
shells of the hydrogen atoms, because their electrons are closer to the
oxygen, take on a small electropositive charge. This means water
molecules have a tendency to form weak bonds with water molecules
because the oxygen end of the molecule is negative and the hydrogen ends
are positive.
A
hydrogen atom, while remaining covalently bonded to the oxygen of its
own molecule, can form a weak bond with the oxygen of another molecule.
Similarly, the oxygen end of a molecule can form a weak attachment with
the hydrogen ends of other molecules. Because water molecules have this
polarity, water is a continuous chemical entity.
These weak
bonds play a crucial role in stabilizing the shape of many of the large
molecules found in living matter. Because these bonds are weak, they are
readily broken and re-formed during normal physiological reactions. The
disassembly and re-arrangement of such weak bonds is in essence the
chemistry of life.
To
illustrate water's ability to break down other substances, consider the
simple example of putting a small amount of table salt in a glass of tap
water. With dry salt (NaCl) the attraction between the electropositive
sodium (Na+) and electronegative chlorine (Cl-) atoms of salt is very
strong until it is placed in water. After salt is placed in water, the
attraction of the electronegative oxygen of the water molecule for the
positively charged sodium ions, and the similar attraction of the
electropositive hydrogen ends of the water molecule for the negatively
charged chloride ions, are greater than the mutual attraction between
the outnumbered Na+ and Cl- ions. In water the ionic bonds of the sodium
chloride molecule are broken easily because of the competitive action of
the numerous water molecules.
As we can see
from this simple example, even the delicate configuration of individual
water molecules enables them to break relatively stronger bonds by
converging on them. This is why we call water the universal solvent. It
is a natural solution that breaks the bonds of larger, more complex
molecules. This is the chemistry of life on earth, in water and on land.
Oxidation-reduction reactions
Basically,
reduction means the addition of an electron (e-), and its converse,
oxidation means the removal of an electron. The addition of an electron,
reduction, stores energy in the reduced compound. The removal of an
electron, oxidation, liberates energy from the oxidized compound.
Whenever one substance is reduced, another is oxidized.

To clarify
these terms, consider any two molecules, A and B, for example.
When molecules
A and B come into contact, here is what happens:
B grabs an
electron from molecule A.
Molecule A has
been oxidized because it has lost an electron.
The net charge
of B has been reduced because it has gained a negative electron (e-).
In biological
systems, removal or addition of an electron constitutes the most
frequent mechanism of oxidation-reduction reactions. These
oxidation-reduction reactions are frequently called redox reactions.
Acids
and Bases
An acid is a
substance that increases the concentration of hydrogen ions (H+) in
water. A base is a substance that decreases the concentration of
hydrogen ions, in other words, increasing the concentration of hydroxide
ions OH-.
The degree of
acidity or alkalinity of a solution is measured in terms of a value
known as pH, which is the negative logarithm of the concentration of
hydrogen ions:
pH = 1/log[H+]
= -log[H+]
What is pH?
On the pH
scale, which ranges from 0 on the acidic end to 14 on the alkaline end,
a solution is neutral if its pH is 7. At pH 7, water contains equal
concentrations of H+ and OH- ions. Substances with a pH less than 7 are
acidic because they contain a higher concentration of H+ ions.
Substances with a pH higher than 7 are alkaline because they contain a
higher concentration of OH- than H+. The pH scale is a log scale so a
change of one pH unit means a tenfold change in the concentration of
hydrogen ions.
Importance of balancing pH
Living things
are extremely sensitive to pH and function best (with certain
exceptions, such as certain portions of the digestive tract) when
solutions are nearly neutral. Most interior living matter (excluding the
cell nucleus) has a pH of about 6.8.

Blood plasma
and other fluids that surround the cells in the body have a pH of 7.2 to
7.3. Numerous special mechanisms aid in stabilizing these fluids so that
cells will not be subject to appreciable fluctuations in pH. Substances
which serve as mechanisms to stabilize pH are called buffers. Buffers
have the capacity to bond ions and remove them from solution whenever
their concentration begins to rise. Conversely, buffers can release ions
whenever their concentration begins to fall. Buffers thus help to
minimize the fluctuations in pH. This is an important function because
many biochemical reactions normally occurring in living organisms either
release or use up ions.

Oxygen: Too much of a good thing?
Oxygen is
essential to survival. It is relatively stable in the air, but when too
much is absorbed into the body it can become active and unstable and has
a tendency to attach itself to any biological molecule, including
molecules of healthy cells. The chemical activity of these free radicals
is due to one or more pairs of unpaired electrons.
About 2% of
the oxygen we normally breathe becomes active oxygen, and this amount
increases to approximately 20% with aerobic exercise.
Such
free radicals with unpaired electrons are unstable and have a high
oxidation potential, which means they are capable of stealing electrons
from other cells. This chemical mechanism is very useful in
disinfectants such as hydrogen peroxide and ozone which can be used to
sterilize wounds or medical instruments. Inside the body these free
radicals are of great benefit due to their ability to attack and
eliminate bacteria, viruses and other waste products.
Active Oxygen in the body
Problems
arise, however, when too many of these free radicals are turned loose in
the body where they can also damage normal tissue.
Putrefaction
sets in when microbes in the air invade the proteins, peptides, and
amino acids of eggs, fish and meat. The result is an array of unpleasant
substances such as:
Hydrogen sulfide
Ammonia
Histamines
Indoles
Phenols
Scatoles
[top

These
substances are also produced naturally in the digestive tract when we
digest food, resulting in the unpleasant odor evidenced in feces.
Putrefaction of spoiled food is caused by microbes in the air; this
natural process is duplicated in the digestive tract by intestinal
microbes. All these waste products of digestion are pathogenic, that is,
they can cause disease in the body.
Hydrogen
sulfide and ammonia are tissue toxins that can damage the liver.
Histamines contribute to allergic disorders such as atopic dermatitis,
urticaria (hives) and asthma. Indoles and phenols are considered
carcinogenic.
Because waste
products such as hydrogen sulfide, ammonia, histamines, phenols and
indoles are toxic, the body's defense mechanisms try to eliminate them
by releasing neutrophils (a type of leukocyte, or white corpuscle).
These neutrophils produce active oxygen, oddball oxygen molecules that
are capable of scavenging disintegrating tissues by gathering electrons
from the molecules of toxic cells.
Problems
arise, however, when too many of these active oxygen molecules, or free
radicals, are produced in the body. They are extremely reactive and can
also attach themselves to normal, healthy cells and damage them
genetically. These active oxygen radicals steal electrons from normal,
healthy biological molecules. This electron theft by active oxygen
oxidizes tissue and can cause disease.

Because active
oxygen can damage normal tissue, it is essential to scavenge this active
oxygen from the body before it can cause disintegration of healthy
tissue. If we can find an effective method to block the oxidation of
healthy tissue by active oxygen, then we can attempt to prevent disease.







Antioxidants block dangerous oxidation
One way to
protect healthy tissue from the ravages of oxidation caused by active
oxygen is to provide free electrons to active oxygen radicals, thus
neutralizing their high oxidation potential and preventing them from
reacting with healthy tissue.
Research on
the link between diet and cancer is far from complete, but some evidence
indicates that what we eat may affect our susceptibility to cancer. Some
foods seem to help defend against cancer, others appear to promote it.
Much of the
damage caused by carcinogenic substances in food may come about because
of an oxidation reaction in the cell. In this process, an oddball oxygen
molecule may damage the genetic code of the cell. Some researchers
believe that substances that prevent oxidation -- called ANTIOXIDANTS --
can block the damage. This leads naturally to the theory that the intake
of natural antioxidants could be an important aspect of the body's
defense against cancer. Substances that some believe inhibit cancer
include vitamin C, vitamin E, beta-carotene, selenium, and gluthione (an
amino acid). These substances are reducing agents. They supply electrons
to free radicals and block the interaction of the free radical with
normal tissue.
How we can avoid illness
As we
mentioned earlier, the presence of toxic waste products such as hydrogen
sulfide, ammonia, histamines, indoles, phenols and scatoles impart an
offensive odor to human feces. In the medical profession, it is well
known that patients suffering from hepatitis and cirrhosis pass
particularly odoriferous stools.
Excessively
offensive stools caused by the presence of toxins are indicators of
certain diseases, and the body responds to the presence of these toxins
by producing neutrophil leukocytes to release active oxygen in an
attempt to neutralize the damage to organs that can be caused by such
waste products. But when an excess amount of such active oxygen is
produced, it can damage healthy cells as well as neutralize toxins. This
leads us to the conclusion that we can minimize the harmful effect of
these active oxygen radicals by reducing them with an ample supply of
electrons.
