CONDENSATION REACTIONS, HYDROLYSIS REACTIONS, AND FUNCTIONAL GROUPS

MOLECULE MODELING KITS • These kits allow us to model molecular structure. They are fun and helpful for learning. • They are NOT TOYS, and they are VERY EXPENSIVE. • Treat them with respect at all times. No throwing • Your kit must be returned exactly as you found it, with the same number of everything in the same place

Failure to follow these guidelines will result in immediate loss of modeling kit privileges.

ETHANOL

Most complex biological molecules are synthesized BY CELLS during anabolic metabolism (anabolism) by way of condensation reactions (i. e. dehydration synthesis) Reaction Catalyzed by an Enzyme

CONDENSATION REACTIONS Show me a condensation reaction with your ethanol molecules Could we connect more than two ethanol molecules this way?

Most complex biological molecules are broken down BY CELLS during catabolic metabolism (catabolism) by way of hydrolysis reactions Reaction Catalyzed by an Enzyme During the evolution of molecular complexity, before the evolution of the first protocells, the appearance of the hydroxyl functional group allowed small molecules (monomers) to combine into larger molecules (polymers).

HYDROLYSIS REACTIONS Show me a hydrolysis reaction with your ethanol molecules

CREATE A MONOMER! • Create a simple monomer that could undergo many condensation reactions. • Build 3 copies of the monomer. • Connect them all together with condensation reactions and show me your resulting polymer, along with all the water molecules created in the process.

Functional Groups: groups of atoms that give the molecules to which they are attached specific characteristics and functions. #Mustmemorize
