Chemistry in our daily life and its importance
A Short Introduction to Chemistry and its branches.
There are five main branches of Chemistry:
1)Organic Chemistry
2)Inorganic Chemistry
3)Analytical Chemistry
4)Physical Chemistry
5)Biochemistry

2. Definition Of Chemistry
• Chemistry is the study of the substances, specially their
structure, properties, transformations and the energy changes
accompanying these transformation.
• Or, the branch of science that deals with the identification of
the substances of which matter is composed; the investigation
of their properties and the ways in which they interact,
combine, and change; and the use of these processes to form
new substances.
3. Some Uses of Chemistry
• Everything is made of chemicals. Many of the changes we
observe in the world around we see that caused by
chemical reactions.
• Chemistry is very important because it helps us to know
the composition, structure& changes of matter. All the
matters are made up of chemistry.
• In our every day like various chemical are being used in
various form, some of those are being used as food, some
of those used clangingetc.

5. • There are five main branches of Chemistry:
Organic Chemistry
Inorganic Chemistry
Analytical Chemistry
Physical Chemistry
Biochemistry
6. Organic Chemistry
• Organic Chemistry is the study of compounds that contain
the elements carbon and hydrogen.
• Or, Organic chemistry involves the study of the structure,
properties, and preparation of chemical compounds that
consist primarily of carbon and hydrogen. Examples:
Petroleum, almost all medicine, food
8. Organic Chemistry
• Organic chemistry overlaps with many areas including-
Medicinal chemistry —the design, development, and
synthesis of medicinal drugs. It overlaps with
pharmacology (the study of drug action).
pharmacology (the study of drug action).
Organometallic chemistry — the study of chemical
compounds containing bonds between carbon and a metal.
Polymer chemistry — the study of the chemistry of
polymers.
9. • The study of compounds that are made of only one or no
carbon elements. It covers all chemical compounds except
carbon elements. It covers all chemical compounds except
organic compounds.
• Inorganic chemistry study things such as crystal structures,
minerals, metals, catalysts, and most elements in the Periodic
Table.
11. Inorganic Chemistry
• Branches of inorganic chemistry include:
Bioinorganic chemistry — the study of the interaction of
metal ions with living tissue, mainly through their direct
metal ions with living tissue, mainly through their direct
effect on enzyme activity.
Geochemistry — the study of the chemical composition
and changes in rocks, minerals, and atmosphere of the earth
or a celestial body.
12. • It is the study of the separation, identification, and
quantification of the chemical components of natural and
artificial materials. It has qualitative analysis which is more on
artificial materials. It has qualitative analysis which is more on
the physical properties and identity and quantitative analysis
the measurement and amount of a certain substance.
• Analytical chemistry involves the qualitative and quantitative
determination of the chemical components of substances.
14. Analytical Chemistry
• Examples of areas using analytical chemistry include:
Forensic chemistry — the application of chemical principles,
techniques, and methods to the investigation of crime.
Environmental chemistry —the study of the chemical and biochemical
phenomena that occur in the environment. It relies heavily on analytical
chemistry and includes atmospheric, aquatic, and soil chemistry.
Bioanalytical Chemistry — the examination of biological materials
such as blood, urine, hair, saliva, and sweat to detect the presence of
specific drugs.
15. Physical Chemistry
• Chemistry that relies on a lot of physics and math to study the
changes in energy that happen to matter.
• The study of the shape of non-living matter and how that
affects matter at the visible scale.
• Physical chemists typically study the rate of a chemical
reaction, the interaction of molecules with radiation, and the
calculation of structures and properties.
17. • Biochemistry is the study of the chemistry in
biological processes of all living organisms. There is
an evident overlapping of different branches of
chemistry but they are all observed in the systems of
chemistry but they are all observed in the systems of
living things.
• Biochemical research includes cancer and stem cell
biology, infectious disease, and cell membrane and
structural biology.
19. • It spans molecular biology, genetics, biochemical pharmacology,
clinical biochemistry, and agricultural biochemistry. Sub-branches of
biochemistry is-
Molecular biology — the study of the interactions between the
various systems of a cell, such as the different types of DNA, RNA,
various systems of a cell, such as the different types of DNA, RNA,
and protein biosynthesis.
Genetics — the study of genes, heredity, and variation in living
organisms.
Pharmacology — the study of mechanisms of drug action and the
influence of drugs on an organism.

72. Conclusion
Now we can say from this presentation that chemistry
is all around us, but the only thin is that we need to
observe it carefully and notice everything around us.
observe it carefully and notice everything around us.
We should appreciate the work of scientists who
observed those things and brought it till us.
