Introduction and definition of Biochemistry

Biochemistry is a study of the chemical nature of living things and the chemical transformation that happen within them. 

Also, deal with the study of the chemical and physical process by means of which the chemical compound such as lipids carbon proteins vitamins and nucleic acids are transformed into one another by the cell itself in order to maintain an organised structure and activities

Biochemistry is a new science in comparison to other the reason for its late blood was sophisticated and concepts need to study the structure and function of all the living system. 

Scope of Biochemistry. 

It sharply defines the term of science it may be said in a general way that biochemistry belongs to all problems of the chemistry of living matters for the chemistry of metabolism. 

Among the more important protein of plant, biochemistry is the chemical nature of chlorophyll the nature and manner of acting of starch formation substance.

The determination of substance out of which plant synthesise its Protoplasm and nature of synthesizing.

In biochemistry in the biochemistry has a avoid used for work isolation of specific Immunizing and other causes. 

Artificial immunity is is a matter of great practical importance biochemistry is the basic offers the foundation and explanation for the essential process of life. 

Bi chemistry is this testing of medicine, for example, try to find a cause of cancer the work recreates the cell and see it is their neutralize disease and also how biochemistry useful for blood testing to see only disease the knowing all body are essential for a disease to try to find the cure of lead found in the system.

Structure of water. 

Water is an abundant component in the living cell. Life activities of cure in the cell due to the presence of water the chemical formula of water is H2O which tell us that two atoms at the hydrogen are joined to one atom of O2 water is Polar molecules, 

Water molecule existent of the bent of geometry.

The bound of the angle of H-O-H is 104.5

And OH bound there exists, electronegativity.

The power of an item in the molecule of attraction of electron this results in the polarization of a positive charge on an O2 + H2O molecule number net charge the polar character of water has the tremendous biological significance of hydrogen bond between H2O molecule biology.

 physical properties of water.

•  water H2O is most evident compound on earth surface coming about 70% of the planet
• It is a dynamic equilibrium between the liquid and Gas state at standard temperature pressure.
• At the room temperature, it is tasteless and odourless liquid colourless with a hint of blue substance dissolve in it.
• H2O it is commonly regarded as a universal solvent because of this water in nature really pure and some of its properties may vary slightly from those and pure substance water is an only common substance found naturally all three States of matter and it essential for all living on Earth it is about 55 to 78% in the human body.

IUPAC  Names Of Water. 

• Water Oxidants
• Hydrogen oxide
•  Dihydrogen monoxide
•  hydrogen hydro. 

Importance of water. 

• Water makes up  70 to 75% of the bodyweight of the average human being. 
• A person can survive for up to four weeks. 
• perform many different functions inside the body it forms the bulk of the essential of transfer nutrients hormones and water delicate balance concentrate within the cell. 
• Water is necessary to carry out the event main basic function of a human being. 
• All living things need water. 
• We cannot substitute other functions without water.
