Organic molecule Wrap up

Wednesday September 25th

.Looking at the following chemical formula, what kind of biomolecule would you infer this to be?  Why?

               C₁₉H₂₈O₂       

this is an example of lipid.  I know this because there is a large amount of Carbon and Hydrogen.  Some of you put Carbohydrates because it has carbon, hydrogen and oxygen but that is incorrect.  While carbohydrates are made up of these same three molecules the RATIO is much different.  Carbohydrates would have MUCH more Oxygen (usually as much oxygen as carbon)

Proteins have MANY different functions – in fact proteins are pretty much involved in ALL cellular functions in one way or another.  The structures of these proteins are incredibly complex.  First, what subunits (monomers) make up protein?

Amino Acids

Next, what determines the function of different proteins?The STRUCTURE directly determines the proteins function.  How the amino acids interact with each other and fold on top of each other determines that structure.

We finished out the Organic Molecules section then I had you complete your introductory activity for a grade

here were the notes for today.
