Condensation Polymerisation And Naturally Occuring Polymers Flashcards
What is made from condensation polymerisation
Polymers
What does condensation polymerisation involve
Monomers that contain different functional groups
What happens to the monomers in condensation polymerisation
The monomers react together and bonds form between them which makes a polymer chain
Why is it called condensation polymerisation
Because for each new bond that forms and small molecule eg water is lost
What do the simplest condensation polymers contain
2 different types of monomer each with 2 of the same functional groups
In condensation polymerisation what is the number of types of monomers
There are 2 monomer types that each contain 2 of the same functional groups
Or
One monomer type with 2 different functional groups
How many products are formed from condensation polymerisation
2 types of products
The polymer and the small molecule like water
What functional groups are involved in the condensation polymerisation
2 reactive groups of each monomer
What types of polymers are found in the natural world
Amino acids
Proteins
DNA molecules
Simple sugars
What 2 functional groups are in amino acids
The amino group NH2 and the carboxyl group COOH
What is the smallest and simplest amino acid
Glycine
What are proteins
Polymers of amino acids
What polymers do amino acids form through what type of polymerisation
Polypeptides via condensation polymerisation
How is a polymer chain formed in amino acids
The amino group of an amino acid can react with the acid group of another amino acid
What is 1 or more chains of polypeptides known as
A protein
What types of proteins are in the human body and what are they ysed for
Enzymes work as catalysts
Haemoglobin transports oxygen
Antibodies from part of the immune system
Majority of body tissue is made from proteins
What changes the properties and shapes of proteins
The order of the amino acids in the polypeptide chain
What is dna made up of
2 polymer chains of monomers called nucleotides
What small molecules do nucleotides contain
A base
What are the 4 different bases in nucleotides called
A C G T
What happens with the bases on the different polymer chains
They pair up and form cross links to give the double helix structure
What do sugars contain
Carbon
Oxygen
Hydrogen
Why do sugars react together and what through
Through polymerisation and it is to form larger polymers like starch and cellulose
