Give name of three natural polymers. Write the place of their iccurance and name of monomers frim which they are formed.
Answers
Explanation:
Polymer is a very large moelcule [macro molecule ] having high molecular mass [10³-10⁷ u] formed by joining of large number of repeating structural units called monomers by covalent bonds .
Based on the source of polymers , these are classified into 3 types :
1. Natural polymers
2. Semi synthetic polymers
3. Synthetic polymers
Natural polymers :
The polymers which are found in plants and animals are called as Natural polymers.
They are :
Starch
Cellulose
Proteins
Starch is condensation polymer made up of number of glucose monomers. It is prepared by plants by photosynthesis process.
cellulose is most abundant organic compound on earth .
Its source is woody part of plants and its available in pure form as Cotton . Its monomers are glucose.
All proteins are condensation polymers of amino acids
