The Molecules of Life

1. Biological olecules

2. Lipids (fats)
Carbohydrates
5 Categories
ATP
Proteins Nucleic Acids

3. Proteins
 Provide strength and
structure
 Process chemical
reactions in
organisms
 Serves as chemical
indicators in the body
for protection

4. Carbohydrates
 Simple and Complex
forms
 Provide energy for
cells
 Provide structure,
toughness, strength,
and protection to
organisms
Simple
Complex

5. Lipids (fats)
 Provide stored energy
 Insulate and protect the
body
 Is the main material for
the outside covering of
cells – the cell membrane
 Phospholipid

6. Nucleic Acids (DNA and RNA)
 Large Molecules that
carrie the genetic code
(instructions to make
proteins)
 The blueprint or
“Encyclopedia of Life”

7. ATP
 Adenosine Triphosphate
 Main fuel source for cells
 Produced by the
breakdown of lipids and
carbohydrates.
