1. Biomolecules

2. What is a Biomolecule?
Life on earth is based on carbon compounds that we call biomolecules.
Biomolecules are macromolecules or “giant molecules.” They are giant because they are polymers made of hundreds or even thousands of smaller molecules called monomers.
Four of the major kinds of biomolecules are carbohydrates, lipids, proteins and nucleic acids.

3. Carbohydrates
Examples are Glucose(sugar), glycogen, cellulose and starch
Functions– the body’s main or primary source of energy
Structure:  elements are carbon, hydrogen and oxygen in a 1:2:1 ratio
Building blocks or Monomers are Monosaccharides (or simple sugar)

4. Carbohydrates

5. Lipids Examples are fat, oil and waxes
Function: long term storage of energy, main structural component of the cell membrane
Structure:  elements are  carbon, hydrogen and oxygen but much less oxygen than carbohydrates; more difficult to break down than carbohydrates
Building blocks or Monomers are Glycerol and Fatty acid chains

6. Lipids

7. Proteins
Examples are muscles, enzymes, antibodies, protein channels, hormones
Function: control rate of chemical reactions, control the movement of molecules across the cell membrane and  major functional component of living things
Structure: elements are carbon, hydrogen, oxygen and nitrogen
Building Blocks or Monomers are Amino Acids

8. Proteins

9. Nucleic Acids Examples are DNA and RNA
Function: to store and transmit hereditary information
Structure:  elements are carbon, hydrogen, oxygen, nitrogen, and phosphorous
Building block or Monomer-- Nucleotide
