1. WHAT IS POLYMERS

2. NATURAL POLYMERS
TOPIC CONTENT
CARBOHYDRATES (GLUCOSE)
PROTEINS
NUCLEIC ACID
NATURAL RUBBER

3. NATURAL POLYMERS
 Occurs in nature & can be
extracted.
 Found in many forms such as horns
of animals ,tortoise shell etc.
 Rubber obtained from sap of the
hevea tree.

4. NATURAL POLYMERS

6. Cotton fiber is mostly cellulose, and
cellulose is made of chains of the sugar,
glucose linked together a certain way.

7. CARBOHYDRATES
 Made up of units of sugar
 Primary function is to provide
energy
 1gram =4.2 kcal of energy
 Are polar molecules i.e., dissolved
in water

9.  CARBOHYDRATES are
divided into 3 groups:
1. Monosaccharides
2. Disaccharides
3. Polysaccharides

10. PROTEINS
 PROTEINS are linear or co-polymer
 Consist of amino acid
 Found in all living bodies

11. TYPES OF PROTEINS
1. Fibrous proteins
• Keratin
• Collagen
• Fibroin
2.Globular proteins
• Enzymes
• Hemoglobin and myoglobin
• Antibodies

12.  “NUCLEIC ACID”
nucleic acid are the polymers of nucleotide
the monomer for all nucleic acid is the nucleotide,
which has three parts
1-PHOSPHATE GROUP
2-FIVE CARBON SUGAR
3-NITROGEN- CONTAINING BASE
(a)ADENINE
(b)GUANINE
(c)CYTOSINE
(d)THYMINE

13. NUCLEIC ACID

14. “NATURAL RUBBER”
 Natural rubber is obtained from HEVEA BRASILIENSIS(cis-
isoprene)
 Natural rubber is a polymer of iso-prene(cis-isoprene)
 The number of iso-prene unit is 11000 to 20000 which linked in
a chain together
PROPERTIES
 It absorb large amount of water
 It has low elasticity and tensile strength
 It is insoluble in water

15. USES:-
Significant tonnage of rubber is used as adhesives
in paper and the carpet industries
many aircraft tires and inner tubes are made of
natural rubber.
