Students should be able to name the types of monomers from which these naturally occurring polymers are made. (HT only) |
|
(Chem only) What are the monomers that form the following naturally occuring polymers?
1. proteins
2. starch
3. cellulose |
|
|
|
Amino acids have two different functional groups in a molecule. Amino acids react by condensation polymerisation to produce polypeptides. (HT only) |
|
(Chem only) What type of polymerisation reaction occurs when amino acids react to form polypeptides? (Include a reason why) Molymods
to create examples of polypeptides |
|
|
|
For example: glycine is H NCH COOH and polymerises to produce the polypeptide (-HNCH2COO-) and n H2O.
(HT only) |
|
(Chem only) What would the equation looks like for the polymerisation of glycine? |
|
|
|
Different amino acids can be combined in the same chain to produce proteins. (HT only) |
|
(Chem only) How are proteins an example of a condensation polymer? |
|
|
|
DNA (deoxyribonucleic acid) is a large molecule essential for life. DNA encodes genetic instructions for the development and functioning of living organisms and viruses. (HT only) |
|
(Chem only) What is DNA and what is its function? |
|
|
|
Most DNA molecules are two polymer chains, made from four different monomers called nucleotides, in the form of a double helix. (HT only) |
|
(Chem only) Why is the structure of DNA described as a polymer? |
|
|
|
Other naturally occurring polymers important for life include proteins, starch and cellulose. (HT only) |
|
(Chem only) What are the other naturally occuring polymers that are important for life processes? |
