Macromolecules
Large molecules
 Macromolecules are formed when
monomers are linked together to form
longer chains called polymers.
 The same process of making & breaking
polymers is found in all living organisms.

Monomers & functional groups
Combinations of different units
Glucose molecule
Formation of starch


Starch is formed from 2 monomer units, glucose
& fructose, which link together via condensation
reaction to produce the disaccharide sucrose.
The enzyme salivary amylase, found in saliva,
hydrolyses starch into its monomer units.
Combination of glucose units
Repeating unit
Amino acid units
Proteins


Proteins are made up of amino acid monomer
units.
The amino end (-NH2) of one amino acid join
up with the acid end (-COOH) of another
amino acid to form a peptide bond.
Monomer/Polymer/Cellular structure
Plastics



Addition polymers are formed by subjecting the
monomer to high pressure & temperature in the
presence of a catalyst.
Polyesters & polyamides (nylon) are synthetic fibers
made from condensation polymerisation.
There are 2 types of plastics : thermoplastics (easily
remoulded) & thermosetting plastics (cannot be remelted or remoulded)
Polymerisation

I am only one, but still I am one. I cannot do
everything, but still I can do something. I will not
refuse to do the something I can do.
