The CHEMISTRY

of LIFE

Elements which is necessary for human body..

There are 90 elements, about 40 of them are found in human body.

C,H, O, N Major elements, 96%

Ca, Fe, Co lesser elements.

Major compounds for life

Minerals

They are simple substances that don’t have subunits. They are natural.

1) carbon, hydrogen, oxygen, nytrogen

They form the structure of organic compounds.

2) Calcium (Ca)

It joins the structure of bone and teeth and is found in milk, egg, yogurt.

In the deficiency, ricket is seen in children.

3) Iron (Fe)

It joins the structure of hemoglobin and is found in yellow egg, spinach.

In the deficiency, anemia is seen.

4) Magnessium (Mg)

It is important for chlorophyll structure

5) Zinc (Zn)

It provides hair extension; in the deficiency, hair falls off.

It is taken into the body by green pepper

6) Iodine ( I )

It joins the structure of thyroxin ;

in the deficiency goiter is seen.

You can take it into your body with onion, garlic, fish, or salts with iodine.

7) Sodium (Na+ ) , Chlorine (Cl- )

Produce electricity with neurons (brain cells).

8) Mo, Mg, Ca, Cu

They join the structure of enzymes

2) Electrolysis (acid, base, salt)

pH amount of the H+ ions inside of the water

Acid

Acids give hydrogen ions into the water; it is used to break down substances.

(lemon, orange, vinegar, green leaf are acid structure)

Base

İt gives OH- ion s into the water. İt is used to increase pH.

Soaps, detergents, toothpaste are base structure.

Salt

Base

acid salt water

Salt

One of the compounds formed from the reaction of an acid with a base.

It balances the blood pressure, so regulates the tension.

Water

the %72 of water in human body.

Water

If there wasn’t any water, the reaction that necessary for life, would stop.

Water should be kept inside of the body. Losing to much water with sweat or diarrhea is dangerous.

Water

Water is an envirnment for some insects.

Water

Water is a good solvent for sugar, protein, biochemical reactions.

This is only reason that we use glucose.

Water

İce point ooC boiling point

100oC This is optimum range

for human body.

It plays the role for regulating temperature of human by sweating.

Water

All matters expand with heat and become with cold.

For water, however, it is opposite situation. Due to continue of life within the water.

Cohesion, adhesion

Cohesion, adhesion

Cohesion water stick to itself by hyrogen bonding, can create surface tension.

Adhesion water stick to other things.

The estimated age of this tree is around 2,300-2,700 years old
