5. Proteins

6. Chemistry in Biology  A compound made of small carbon compounds called amino acids  Amino acids are small compounds that are made of carbon, nitrogen, oxygen, hydrogen, and sometimes sulfur. Chapter 6 Proteins

7. Amino acids (monomers) are the basic building blocks of polypeptides (polymers) and polypeptides form proteins. Functions: –structural components of cells –catalyzing chemical reactions (enzymes) –transporting substances within cells –messenger molecules (hormones) Characteristics of Proteins

8. Chemistry in Biology  Amino acids have a central carbon atom.  One of the four carbon bonds is with hydrogen.  The other three bonds are with an amino group (–NH 2 ), a carboxyl group (–COOH), and a variable group (–R). Chapter 6 Proteins

9. Chemistry in Biology Chapter 6 Proteins

10. Chemistry in Biology  The number and the order in which the amino acids are joined define the protein’s primary structure.  After an amino acid chain is formed, it folds into a unique three-dimensional shape, which is the protein’s secondary structure, such as a helix or a pleat. Chapter 6 Structures of Proteins

11. Write of brief, comprehensive summary (3-4 sentences) of your notes, focusing on the main ideas and concepts. Be prepared to share you summary with your classmates. Summary

12. Chemistry in Biology  Nucleic acids are complex macromolecules that store and transmit genetic information.  Nucleic acids are made of smaller repeating subunits called nucleotides, composed of carbon, nitrogen, oxygen, phosphorus, and hydrogen atoms. Chapter 6 Nucleic Acids

14. Chemistry in Biology Chapter 6 Building Blocks of Life

15. Write of brief, comprehensive summary (3-4 sentences) of your notes, focusing on the main ideas and concepts. Be prepared to share you summary with your classmates. Summary
