3. Amino acids
vDefination:
The organic compound which contain both
amio acid and carboxlic group then that is called
amino acids
vExample:
ØGlycene Alanine

4. Importance of amino acids:
v Amino acid are the building blocks of
protein about 20 amino acids have been
about in protiene
v All naturally occuring amino acids
arecalled alpha amino acids because
amino group is bounded to a alpha carbon
Genral formula
ofamino acids

5. Types of amino acids

6. v The amino acids which contain one
carboxlic group and one amino group are
called natural amino acid
Glycene Alanine
Natural Amino acidsx

7. vThe amino acids which contain two carboxyl
group are called acidic amino acids
• Aspartic acid glutamic acid
Acidic Amino acidsx
Examples

8. • The amino acids which contain two amino
groups and one carboxyl group are called
basic amino acids
Lysine. Histidine.
Basic Amino acids
Examples

9. “ The Amino acids which can be synthesed
within the body are called non-essential amino
acides”
“The amino acids which can not be synthesized
within the body are called the essential amino
acides”
Essential & non essential Amino acids

10. vAmino acides can be named by
IUPAC nomenclature .However
these are given as common or
trivel names these common name
are given according to the origin
or some property of amino acids
Nomenclature of Amino acids

11. because it was isolated from cheese
is abbrivated as
is abbrivated as
Examples

12. • The structure of Amino acid from dipolar
ion or zwiter ion .It has both positive ends
and negitive ends .In the formation of
proton from the carboxyl group goes to
amino group
Structures of Amino Acids
Example

13. • When an acid is added to an amino
acid .then its carboxilate ion accepts a
proton therefore amino acids shows basic
character
Acidic & basic character of amino acids

14. • Amino acids can be synthesized by two
methods
v By the reaction of alpha-bromo Acid with
Amonia
The recation of @-bromo acid with amonia gives
Syntheses ofAmino Acids

15. Strecker syntheses

16. An Amino acids ract with an alcohol to form
an amino ester
Reactions of Amino acids

17. • An Amino acid reacts with nitrous
Acid(HNO3) to form a-hydroxy carboxlic
acid
Reaction with nitrous Acid

18. Ninhydrin reacts with
amino acid to form a product with deep bluish
violet colour
• It is also used for sepretion of Amino acids
by paper chromatography
