2.  Introduction to Protein.
 Definition of Protein.
 Feature of Protein.
 Properties of protein.
 Classification of Protein .
 Structure of Protein .
 Function of Protein.
 Conclusion

3.  Proteins are important molecules of
cells.Protein are the major component of
the dry weight of cells.
 The name was first sugggested in 1838 by
a swedish chemist Berzelous.
 Protein are known as the building blocks
of life .Protein are consist on one or more
chains of amino acid.

4.  Protein is a complex organic nitrogenous
compound composed of amino acid
linked together by peptide bonds.
 Protein is a high molecular-weight
polypeptide made up of amino acid linked
together by polypeptide bonds.

5.  Most important biomolecules. they are the
fundamental constituent of the cytoplasm of the
cell.
 Structural elements of body tissues.
 Proteins are considered as the bricks, they make
up bones, muscles, hair and other parts of the body.
 Proteins like enzymes are functional elements that
take part in metabolic reactions.
 Antibodies, blood haemoglobin are also made of
proteins.

6.  Physical Properties…
 Proteins are colorless and tasteless.
 They are homogeneous and crystalline.
 Proteins vary in shape, they may be simple
crystalloid structure to long fibrilar structures.
 The diffusion rates of proteins is extremely
slow.
 Proteins exhibit Tyndall effect.

7.  Hydrolyzed by acidic agents.
 Reaction with alcohols & gives esters.
This process is known as esterification.
 Amino acids reacts with amines to form
amides.
 Protein gives Sanger reaction.
 Protein gives Xanthoproteic Test.
 Protein gives Folin’s test.

8. Three types of Protein
Simple Protein
Protein
Conjugated
Protein
Derived
Protein

9.  These proteins are made of only one type of amino
acid, as structural component, on decomposition
with acids, they liberate constituent amino
acids.Simple proteins are further classified based
on their solubility.
Name Example
Albumins Leucosine, legumeline, serum albumin
Globulins Pseudoglobulin, serum globulin, glycinine
Protamines salmine, clupine, cyprinine
Histones nucleoshistones, globin.
Scleroproteins Animal skeleton proteins.

10.  These are proteins that are made of amino acids
and other organic compounds. The non-amino acid
group is termed as prosthetic group. Complex
proteins are further classified based on the type of
prosthetic group present.
Name Example
Metalloproteins casein, collagen, ceruloplasmin
Chromoproteins Myoglubin, hemocyanin, cytochromes
Glycoproteins egg albumin, serum globulins, Mucoproteins
Phosphoproteins casein
Lipoproteins lipovitellin, lipoproteins of blood
Nucleoproteins Nucleoproteins, nucleohistones, nuclein.

11.  These are proteins that are derived from the action
of heat, enzyme or chemical reagents.Derived
proteins are of two types, primarily derived proteins
and secondary derived proteins.
 Primary derived proteins are classified into three
types: - Proteans, Infraproteins and Coagulated
proteins. Example: edestan, coagulated eggwhite.
 Secondary derived proteins are further classified
into 3 types: - Proteoses, Peptones and
Polypeptides.

12. Primary
Structure
Secondary
structure
Tertiary
Structure
Quaternary
Structure
Four types of Structure

13.  Primary Structure of Protein:
 Primary structure of protein is the linear
sequence of amino acids that make up the
polypeptide chain.
 His sequence is given by the sequence of
nucleotide bases of the DNA in the genetic
code.
 Secondary Structure of Protein:
 The folding of the polepeptide chain into a
specific coiled structure held together by
disulfide bonds and hydrogen bonds is
knows as the secondary structure of
protein.

14.  Tertiary Structure of Protein:
 Tertiary structure of proteins is the three
dimensional structure formed by the bending and
twisting of the polypeptide chain.The overall
arrangement and interrelationship of the various
regions, or domain and individual amino acid
residues of a single polypeptide chain is known as
the tertiary structure of protein.
 Quaternary Structure of Protein:
 Some proteins contain more than one polypeptide
chains, this association of polypeptide chains refers
to the quaternary structure.Each polypeptide chain
is called a subunit.

15.  Found in muscles, hair, skin and
other tissues, E.g: keratin, is
present in nails and hair.
 Some protein act as hormones
Example: Insulin hormone.
 Act as enzymes. E.g: Pepsin and
Tripsin.
 Act as antibodies.

16.  Transport substances in blood of
different tissues. E.g: Haemoglobin
is a oxygen transport protein.
 Contraction of muscle and cells .E.g:
Myosin.
 Prevents blood loss.E.g:Fibrinogen.

17.  At last now we are clearly informed about
the Protien,what's it and what it's
Features and properties,what it's
important along to our body.Protein are
the most essential element for our body.It
can be uses For developing our body in
various purpose.
