Download -body stores fat in special cells filled with fat globules.

-body stores fat in special cells filled
with fat globules.
-mostly under the skin and in the
abdominal cavity.
-your liver will change fat into
glucose in order to get energy
3. PROTEINS

Made of chains of amino acids
3D
that are wrapped into a
shape to make protein
Different proteins
have
different amino acids
or
different orders
Ex.
Protein 1=
L+I+V+E
Protein 2=
E+V+I+L
Same amino acids,
How does your body know what
order the amino acids should be
in?

Your DNA contains
the information the
body needs to
make the proteins
3. PROTEIN

IMPORTANCE
Repairing
damaged body
tissue
WARNING GRAPHIC
MATERIAL

Building tissue
(including muscle)

Act as enzymes
(run chemical
reactions)
break down
(digestive
enzymes)
build up
(actin in the
muscles)
There’s more!

Carrier molecules
(ex. Hemoglobin in
blood)

Cell tags
Everyone has different
protein tags on their
cells!

Help materials
move in and out of
cells
Examples of Proteins




Beans
Meats
Eggs
Nuts


There are 20 different amino acids
found in our food
Only four are made by your body!
Your body is made almost entirely
of protein.


Skin
Nails
Hair
Organs
Muscle
4. Nucleic Acids


IMPORTANCE
Contain a chemical code
Contains directions for the body to
function
Two Types of Nucleic Acids
1.



DNA
Deoxyribonucleic acid
Passed from parents to offspring
Contain information for your looks,
personality and metabolism
(chemical reactions in the body)
2.



RNA
Ribonucleic acid
Kind of like DNA’s message taker
Helps DNA make proteins
