2. Proteins
It is polymer of amino acids
Proteins form structure of body
C,H,O,N are present

3. Structure Protein: Amino Acids

4. Amino Acids These are taken by food not in body
Essential amino acids
These are taken by food not in body
i.e. indispensable amino acids
PVT. TIM HALL (or PVT. MAT HILL)
Nonessential amino acids
These are formed in body
i.e. dispensable amino acids
“Conditionally” essential amino acids

6. Peptide bond
It is of three type dipeptide, tripeptide,polypeptide
A peptide bond is between –NH2 of one amino acid and –COOH of another

7. Dipeptide

8. Tripeptide

9. Polypeptide

10. Formation of peptide bond
4 types
Primary
secondary
tertiary
quaternary

11. Primary peptide Secondary peptide
These are formed by a single polypeptide chain linear manner
All amino acids are attached in a straight chain by peptide bond
Secondary peptide
These are of two types
α helix and β pleated sheet

12. Tertiary peptide Quaternary peptide
In this structure of protiens atom are highly coiled and form a spherical form
Hydrogen ,ionic ,hydrophobic,disulphide bond
Quaternary peptide
When 2 polypeptide bond are united by covelent bond is called quaternary bond

13. Types of protein
3 types
Simple
conjugated
derived

14. Simple Conjugated These are of two types Fibrous and globular
Fibrous:- it is soluble and their main function is protecting
Globular:- it is insoluble and
Conjugated
These are complex proteins in which protein is combined with characteristic non amino acid substance

15. Derived
These are obtained as a result of partial hydrolysis of natural protein .
Eg proteose ,metaproteins
