The importance of water in our daily lives

Importance Of Water in our daily life the water is tasteless, almost colorless, and blue in color. Water is the center of life. It is the most abundant complex of all living things. In different organisms, this percentage varies from 65% to 89%. About 20% of bone cell water occurs in human tissues in the presence of water. Water involved in many biochemical reactions, such as molecular hydrolysis. Its used as a raw material for photosynthesis. The importance Of Water in Biochemistry here discuss below.

Uses And Importance of Water

1. The role of water in chemical reactions

All reactions carried out in the presence of water. He involved in many biochemical reactions. For example, water causes the hydrolysis of large particles. Water used for photosynthesis.

2. Solvent properties

Water is a polar or ionic molecule. Therefore, it is an excellent solvent for polar materials.

Ionic substances dissolve in water and dissolve into positive ions and negative ions. Ionic compounds have charged groups in their molecules. Therefore, they dispersed in water. Ions and molecules move randomly in solution. Therefore, they can easily interact with other molecules and ions. Because of this characteristic, all reactions occur in the cell’s aqueous medium in the presence of enzymes. These enzymes only work in an aqueous environment.

Non-polar molecules such as fats are insoluble in water. Therefore, these compounds form cell membranes.

3. Heat capacity

The number of calories required to raise a temperature of 1 gram of water from 15 to 16 called the specific heat capacity of water.

The specific heat capacity of the water is 1.0. Without changing its temperature, the water has a strong ability to absorb heat. Therefore, water acts as a temperature stabilizer for living things in the environment. It can protect biological materials from sudden thermal changes.


Specific heat capacity defined as the energy required to raise the temperature of a constant amount of material. Boiling requires 100, likewise, the temperature will drop very slowly. This temperature stability plays an important role in cells.

4. Heat of evaporation

The heat required to convert 1 gram of water into vapor called the heat of vaporization or the specific heat of vaporization. Its expressed in calories/gram. The specific temperature of water evaporation is 547 kcal/kg. Therefore, when switching from liquid to gas, the water absorbs a lot of heat. Therefore, water regulates the heat generated during oxidation. It also cools the plants during the transpiration process. The animals cool down as the water evaporates. Evaporating only 2 ml of water from one liter of water can reduce the remaining 998 ml of water temperature by 1.

5. Ionize the water

Molecules ionize to form ions, and this reaction is reversible. However, maintaining balance. The total concentration in freshwater at 25 ° C is about 10 moles/liter. Ions influence and participate in many reactions in the cell.

6. Protection

Water is a lubricant. Reducing friction. Therefore, it can protect the body parts from damage. For example, tears can protect the eyes from rubbing the eyelids. It forms a protective layer of fluid around the organ and protects the organ from shock.

7. The water is hermaphrodite

The water acts as an acid and a base. As an acid, it releases electrons to form H +, and as a rule, it takes electrons to form OH. The water capacity of amphibious molecules and helps to rapidly change the enzyme activity medium.

Water act as Amphoteric Molecule

8. Cohesion

Due to the presence of OH ions, cohesion has been lost. This cohesive force helps to increase plant juice and helps different materials pass through the vascular bundle.

9. Chemical formula

It is basically DIPOLE. Hydrogen atom electrode + atom end and the oxygen atom has to blink. The most important consequence of this charge separation is the tendency of water molecules to form hydrogen bonds.
