Monomers

Polymer

Biomolecules are large organic molecules found in living things.

On the picture, which part represents a monomer?

Carbohydrates

Polymer

Polysaccharide

Monosaccharide

Living things use carbohydrates as sources of energy and for
structural purposes.

Match

Match the following terms with the correct descriptions

• Monosaccharide

• Polysaccharide

• Disaccharide

Carbohydrate Monomers

Carbohydrate Polymers

Two Monosaccharides bound together

• Carbohydrate Monomers

• Carbohydrate Polymers

• Two Monosaccharides bound together

Carbohydrates

Not all polysaccharides are the same.

Your body can’t digest
cellulose because of
the direction of the
bond.

We commonly call
cellulose we eat, fiber.

Lipids

Unsaturated

Lipids are a large and
varied group of
biomolecules that are not
generally soluble in
water.

There are three common
types of Lipids.

The one on the right is a
Triglyceride.

Lipids

Phospholipids have a phosphate head which
is hydrophilic and a lipid tail which is
hydrophobic.

Nucleic Acids

DNA and RNA are
two common Amino
acids.

The DNA pictured here, is made of two chains of nucleotides stuck together.

Fill in the Blanks

Name one common type of nucleic acid:

Proteins

There are 20
amino acids
coded for by
your DNA.

9 are
Essential
because
they have to
come from
your food

Multiple Choice

Which part of an amino acid can be different from one amino acid to the next?

• The Carboxyl Group

• The Amine Group

• The R Group

Fill in the Blanks

Your body can not produce all 20 amino acids. Some of them are called "Essential Amino Acids" because they have to come from our food. How many "Essential Amino Acids" are there?

Protein Structure

A protein is a functional molecule built
from one or more polypeptides.

Proteins have for layers of structure.

Many proteins in your body are
enzymes.

Fill in the Blanks

Proteins have how many layers of structure?

Enzymes are
proteins that act
as little machines
to speed up
reactions.
