Monomers and polymers

1.

Monomers and polymers

2.

Lesson objectives
To learn differences between monomers
and polymers

3.

When you eat food, your body uses it
to produce energy and as a raw
material. But food is bigger than a
cell. How does it enter into a tiny cell?

4.

Most of the nutrients are made up of
organic compounds.
Large organic compounds are called
MACROMOLECULES.

5.

There are 4 main macromolecules:
1) Carbohydrates
2) Lipids
3) Proteins
4) Nucleic acids

6.

POLYMERS
Some
macromolecules are
polymers.
Polymers are large
molecule composed
of repeated units
linked together.
Repeated units of
polymers are called
as MONOMERS.

7.

Carbohydrates, nucleic acids, proteins are
polymers
Lipids are NOT polymers

Food macromolecules
are mostly polymers.
They are broken down
into monomers by
digestive system.
Monomers are small
enough to enter the
cell.
