,Overview: The Molecules of Life
• All living things are made up of four classes
of large biological molecules:
– carbohydrates,
– lipids,
– proteins, and
– nucleic acids
• Macromolecules
• are large molecules
• composed of thousands of covalently connected atoms
– Concept 2.3 ( for more information)
» A covalent bond is the sharing of a pair of valence
electrons by two atoms

, • A polymer is
• a long molecule
• consisting of many similar building blocks
• These small building-block molecules are called
monomers


• Three of the four classes of lifeʼs organic
molecules are polymers
– Carbohydrates
– Proteins
– Nucleic acids 4

,The Synthesis and Breakdown of Polymers
• Synthesis of polymer from monomers:
– By dehydration reaction
• when two monomers bond together ???
– through the loss of a water molecule

,• Breakdown of Polymers to monomers :
– By hydrolysis reaction
• the reverse of the dehydration reaction ??

,The Diversity of Polymers
• Each cell has thousands of different
macromolecules
HO




• Macromolecules vary among
– cells of an organism,
– vary more within a species,
– and vary even more between species


• An immense variety of polymers can be built
from a small set of monomers
