How Are
Macromolecules
Formed?
1
Answer: Dehydration Synthesis
 Also
called “condensation
reaction”
 Forms polymers by combining
monomers by “removing water”.

Dehydration Synthesis

Monosaccharides can be linked together through the
process of Dehydration Synthesis
–


Water is removed from 2 monocaccharides - resulting in a
covalent bond between the 2 molecules
Sucrose (table sugar) is made of 2 sugars linked
together and these are called Disaccharides
Require some digestion to be used by cells
Hydrolysis


Dehydration synthesis is a reversible process Called Hydrolysis.
A water molecule is inserted where the monomers join. Breaking
their bonds.
