what raw materials do the human body contain?

Answer 1

All kinds of stuff in small amounts. Here's what the majority of it is:


Molecule..........Mass %...Molecule %

Water................65% .........98.73 %
Other Inorganic...1.5% ........0.74 %
Lipid..................12% ..........0.475 %
Other Organic....0.4% .........0.044 %
Protein..............20% ..........0.011 %

RNA..................1.0% ........3 x 10-5 %
DNA..................0.1% ........3 x 10-11 %

In other words, pretty much everything is water, protein, and fats.

If you go by elements, 99% of the human body weight is made of oxygen, carbon, hydrogen, nitrogen, and calcium (in that order). Nothing especially valuable or rare there.

Answer 2

Lots of water, and a sprinkling of every chemical out there.
