I want to ask about the chemical composition of human beings can you tell me?

Question

anything about it? Is every persons chemical makeup just the same, if so why? If it is not how can it be different? How variable can it be?

Thank you guys for being honest and for that invite. I am happy to have them hope that I get some more. It is good.

I am getting some good answers, but I am not sure if I am getting answers particular to what I have asked here maybe I am not asking it well, yes I want you to tell me what I am asking, smile. You guys are doing great!

Answer 1

First off, let's define "chemical." A chemical is anything that is made up of more than one atom. Water is a chemical.

96.1% of the human body is comprised of carbon, hydrogen, oxygen and nitrogen.

3.9% of the human body is comprised of calcium, phosphorus, potassium, sulfur, sodium, chlorine, magnesium, iodine, and iron.

Trace Elements (less than .01%) in the human body include chromium, cobalt, copper, flourine, manganese, molybdenum, selenium, silicon, tin, vanadium, and zinc. These elements are called "trace elements" because they are required in very minute amounts; many are found as part of enzymes or are required for enzyme activation.

Water is the most abundant chemical compound in the human body making up 60 to 80% of the volume of most living cells.

Salts are ionic compounds that contain cations other than H+ and anions other than OH-. These are referred to as electrolytes because, when desolved in water they form ions(substances capable of conducting electrical currents). Our bodies need to take in these substances because they are sources of necessary ions that help make many metabolic reactions possible.

Acids and Bases are also referred to as electrolytes as they, too, are a source of necessary ions.

It is the ions, rather than the salts, acids, and bases that the body needs. These chemicals (of which there are hundreds) are taken in through our diet and then broken down during the digestive processes and absorbed in the form of the necessary ions.

Our body's major molecules can be broken down into four main groups: carbohydrates (sugars and starches); lipids (includes neutral fats, polar fats, steroids and waxes); proteins; and nucleic acids (DNA and RNA).

In addition to water, an inorganic molecule, the body also requires oxygen which is utilized to break down glucose thus releasing the energy locked up in our food to generate energy for cellular metabolism.

Answer 2

their is no chemical equation for any organism, however, in terms of chemical composition, every human is going to produce most of the same by products; such as CO2, H2O, Urea, lactic acid just to name a few. However when it comes to DNA, every human is different, so humans may have more enzymes than others, or some may be deficient in certain enzymes. Enzymes and proteins are really the only discrepancies between people, that and the exact genetic makeup at the nucleotide level. For the most part all humans will produce the same chemicals, maybe some humans will beable to deal with some chemicals better than others, or work reactions faster than others, but none-the less we are pretty similar chemically.

Answer 3

The chemical makeup of our bodies are the same as that of the earth we live on. The calcium, water and other minerals of the body is in the same proportion as the earth. We ingest the earth and therefore are part of the earth.

Answer 4

How about 3 trillion angels ! All doing their part to help you exist in the natural ?!

Answer 5

putting it in laments terms,we are composed of water and carbon(sorry Al Gore,I guess im my own footprint)
