What does “biomolecule” mean? “bio” = living, life “molecule” = smallest unit of a chemical compound Therefore…?

Biomolecules are the molecules found in all living things Biomolecules are the molecules found in all living things. They are necessary for LIFE.

So…where do these come from. What are they made of So…where do these come from? What are they made of? To figure that out, we have to start at the beginning…

1. Biochemistry…The Basics Matter: anything that has mass and takes up space Element: matter made of only one type of atom Atom: basic units of an element only one type of element

The Fab Five Elements In Biology this year, we will be focusing on 5 main elements. They are… Carbon Hydrogen Oxygen Nitrogen Phosphorus

That’s 96.8% of your total body composition! Notice just how much of the human body they compose That’s 96.8% of your total body composition!

Carbon in Chemical Structures Carbons are represented By the letter C Carbon is so common in living organisms that they can sometimes be omitted to save time. Anywhere there is a corner without a letter, that means a carbon is actually there.

Hydrogen in Chemical Structures Hydrogen is represented By the letter H

Nitrogen in Chemical Structures Nitrogen is represented By the letter N

Phosphorus in Chemical Structures Phosphorus is represented By the letter P

Directions: Label one example of each element on your practice page Directions: Label one example of each element on your practice page. Color code the remaining elements C=green, H=blue, O=orange, N = pink, P=purple. Highlight the bonds in yellow.

Organic Compounds Compounds containing the element Carbon Basis for living matter

Polymers (many parts) Monomers (one part) Macromolecules Large molecules that are formed by joining smaller molecules Polymers (many parts) macromolecules made from repeating units of smaller molecules. Monomers (one part) a single unit which is bonded together

Bonds, bonds, bonds! Molecules are atoms bonded together. The bond stores energy. When that bond is broken, energy can be released.

Chemical Reactions Chemical reactions are how atoms bond together and break apart. When a chemical reaction breaks a bond, energy can be release in the form of heat.

Parts of a Chemical Reaction Arrow: “yields”, makes C + O2  CO2 CO2 Reactants: what goes INTO the chemical reaction, left side of arrow Products: what is produced from the reaction, right side of arrow Chemical Reactions in a Cake

Biomolecules 4 major biomolecule: Carbohydrates Lipids Proteins Nucleic acids We find biomolecules in our FOOD!

Making/breaking polymers is part of metabolism.

Dehydration synthesis = a process through which polymers are formed from monomers through the removal of H2O.

Hydro=water Lysis=cut Hydrolysis = the process of breaking down polymers into monomers by the addition of H2O. Hint: Think red rover

Copy and answer the following questions (on back of lab notes) The glue contains a polymer called polyvinyl acetate resin. We changed the polymer’s behaviors twice in this activity; once when we added water and the second time when we added borax. Copy and answer the following questions (on back of lab notes) When we added water, what process was occurring; dehydration synthesis or hydrolysis? Describe the glue after water was added. When we added borax, what process was occurring; dehydration synthesis or hydrolysis? Describe the glue after borax was added.
