Page 1: Proteins Enzymes are Proteins. Proteins Proteins: a chain of amino acids 20 different amino acids are found in proteins

Proteins Enzymes are Proteins

Page 2: Proteins Enzymes are Proteins. Proteins Proteins: a chain of amino acids 20 different amino acids are found in proteins

Proteins

• Proteins: a chain of amino acids

• 20 different amino acids are found in proteins

Amino Acid Structure

Page 5: Proteins Enzymes are Proteins. Proteins Proteins: a chain of amino acids 20 different amino acids are found in proteins

Amino Acid + Amino Acid

• Amino acids are linked together via covalent bonds (electrons are shared).

• Does this polymer have more or less energy than NaCl? Why?

Page 6: Proteins Enzymes are Proteins. Proteins Proteins: a chain of amino acids 20 different amino acids are found in proteins

Dehydration Synthesis

• H2O molecule is released

• When talking about proteins, it links together amino acids. • aka peptide bond formation

Dehydration Synthesis

• Practice

Protein Folding

• Charges on proteins interact • Positively charged • Negatively charged• Polar • Non- polar

• Which charges “like” each other?

• Which charges “dislike” each other?
