Water: constantly being assembled and dis-assembled

This is about health/biochemistry in general, not the primal diet. As I have been studying biochemistry recently, I have been FLOORED by what I have learned about the variety of chemical reactions involving water (and not just liquid crystal “structured” water with extra electrons/negative electromagnetic charge/alkaline pH). I have been thinking of water as if it is an element (like a basic unit of matter). WRONG!

 

For instance, most combustion (i.e. burning, heat, inflammation) produces H2O (water vapor/steam) as a by-product (as well as carbon dioxide). WTH?!?!?

Water molecules are constantly being both decomposed and rebuilt in living creatures (and elsewhere). I have been thinking of water in a “zero-sum” way: like that I drink or soak in water, which eventually gets expelled by urine or perspiration, etc…. NO! Water is constantly being assembled and dis-assembled.

 

For any fellow nerds out there, almost everything below is copied and pasted:
aerobic cellular respiration of carbohydrates:

C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (as ATP)

In laymen terms, carbs and inhaled oxygen -> exhale carbon dioxide and (water) vapor, using energy for the cells (ATP is “the currency or energy of the body” … which is ultimately about electrons)

 
(stomach acid + lye –> salt + water … or saltwater)

HCl + NaOH ——> NaCl + H20

 

 

The electrolysis of water into oxygen and hydrogen gas is an example of a decomposition reaction:

2 H2O → 2 H2 + O2
Acid-Base Reaction:
An acid-base reaction is type of double displacement reaction that occurs between an acid and a base. The H+ ion in the acid reacts with the OH- ion in the base to form water and an ionic salt:

HA + BOH → H2O + BA

The reaction between hydrobromic acid (HBr) and sodium hydroxide is an example of an acid-base reaction:

HBr + NaOH → NaBr + H2O

 

Combustion:
A combustion reaction is a type of redox reaction in which a combustible material combines with an oxidizer to form oxidized products and generate heat (exothermic reaction). Usually in a combustion reaction, oxygen combines with another compound to form carbon dioxide and water. An example of a combustion reaction is the burning of naphthalene:

C10H8 + 12 O2 → 10 CO2 + 4 H2O

 
As a reactant (one of the starting compounds):

Here is an example of a chemical reaction that involves H2O as a reactant:
Bi + 4HNO3 + 3H2O = Bi(NO3)3.5H2O + NO

There are simpler ones:
2Na + 2H2O → 2NaOH + H2

Mg + 2H2O → Mg(OH)2 + H2

Rusting of iron:
2Fe+O2+H2O→Fe2O3+H2
