Please do the following: -pick up the handouts from the front table -have out your notebook -turn in your Biomolecules Test to the tray, please have the rubric stapled to it Happy Monday!

Polymer: chain Monomer: link

Synthesizing & Digesting: Two basic reactions: 1) Dehydration synthesis –Dehydration – water lost –Synthesis - build = removing a water molecule to build a polymer!!

Synthesizing & Digesting: 2) Hydrolysis –Hydro – water –Lysis – break apart = Using water to break apart polymers! DIGESTION!!!!!!!!

With a partner, define a monomer and a polymer… What is another everyday example you can think of that have monomers and polymers?

cell wall Cellulose

With a partner, discuss the following question: What are two ways that carbs and lipids are alike?

RNA

Peptide Bonds

IMPORTANT: The order of the amino acids determines the shape of protein The order of the amino acids determines the shape of protein Shape determines FUNCTION Shape determines FUNCTION !

 Primary Structure is just the specific order of amino acids in the chain.  Secondary Structures are either a helix or a pleated sheet formed form hydrogen bonds reacting between the amino acids.

 Tertiary Structure occurs because of attractions between the alpha helices and pleated sheets.  Quaternary Structure is a protein consisting of more than one amino acid chain.

With a partner, discuss the following question: How are carbohydrates and nucleic acids related?

Enzymes

Proteins Carbohydrates Lipids Nucleic Acids

With a partner, discuss the following question: How do we obtain carbon from the carbon cycle?
