Polymers, Amino Acids, Protein & DNA Flashcards
Define addition polymerisation
An addition polymer is a long chain formed from many monomers and no other product is formed
Do addition polymers biodegrade
No
They have C-C (carbon-carbon bonds) that are non-polar so can not be attacked by nucleophiles
Look, cover, write ,check
Define condensation polymerisation
In a condensation reaction, 2 molecules join to form a larger one, with a small molecule such as H2O or HCL being released
What are the 2 types of condensation polymers and what are they made of
Polyesters:- C.Acid and Alcohols
Polyamides:- C.Acid and Amines
Fill in the blanks
Give the general formula for condensation polymers
Give uses of Terylene
+ 2n-1 H2O
Terylene: Carpets, clothing
Fill in blanks
Uses and properties of Nylon and Kevlar (polyamides)
Nylon used as fibers in clothes
Elastic, strong abrasion resistant
Kevlar used to manufacture body armor and crash helmets
Strong, light, and heat resistant
Are condensation polymers biodegradable
Draw a Zwitterion
Describe the bonding in the secondary structure of a protein
-Hydrogen bonding between H-O/N-H
-Which causes a large difference in electronegativity between the δ+ on the H and the lone pair of electrons/ δ- on the O
-C=O is planar
