The Building Blocks of

In your table groups make as many observations as you can about the diagram on the left.

Of the naturally occurring elements on earth, only about 25% are essential to living organisms. In fact, only four of the elements Carbon, Hydrogen, Oxygen & Nitrogen together make up more than 96% of the mass of a human body.

Without these compounds, cells could not function. Organic compounds contain carbon atoms. There are four principal classes of organic compounds found in all living things:

What chemical elements make up these molecules? What chemical elements make up these molecules? They are made up of building blocks called They are made up of building blocks called monomers, but what are they? monomers, but what are they? What are some examples of these biomolecules? What are some examples of these biomolecules? What is their function? What is their function?

 Create a data table like the one on the right in your notebook

Working in groups of 3 or 4, use your Biomolecules outreach notes to complete the table.

Carbohydrates Elements its made from: Monomers (building blocks): Examples: Functions: Chemical structure: C, H, O Monosaccharides sugars, starches, glycogen, cellulose main source of energy for cells

Lipids Elements its made from: Monomers (building blocks): Examples: Functions: Chemical structure: C, H, O Fatty Acids & Glycerol Fats, oils, waxes, steroids Long term energy storage, major component of cell membrane

Proteins Elements its made from: Monomers (building blocks): Examples: Functions: Chemical structure: C, H, O, N Amino Acids Muscles & enzymes Structure, regulates cellular processes & chemical reactions

Nucleic Acids Elements its made from: Monomers (building blocks): Examples: Functions: Chemical structure: C, H, O, N, P Nucleotides DNA & RNA Stores and transfers genetic information

C, H, O Monosaccharides sugars, starches main source of energy for cells C, H, O fatty acids & glycerol fats, oils & waxes store energy, cell membrane C, H, O, N amino acids muscle, enzymes Regulate cellular processes & chemical reactions C, H, O, N, P nucleotides DNA & RNA Store and transfer genetic information

Each section (flap) should contain the following information: Function of the biomolecule; Elements involved (carbon, hydrogen, etc.) Monomers (ex: building blocks – what are they made up of) Examples (ex: sugars, fats, etc.) Carbohydrates: * Function * Elements Involved * Monomers Building Blocks Sub Units * Examples * Drawing structure Begin research on page 157 of your textbook.
