Lecture AP Biology - Chapter 5: The structure and function of large biological molecules

In this chapter, you should be able to: List and describe the four major classes of organic molecules; Explain: monomers, polymers, dehydration synthesis with the type of covalent bond for each; distinguish between monosaccharides, disaccharides, and polysaccharides. | Warm-Up What are the 4 classes of macromolecules? Give an example of each. Draw and label the parts of an amino acid. How are 2 amino acids put together? Name the process and describe what happens. Draw a tripeptide. (Use Google for help) Label the peptide bonds. Peptide Bonds Warm-Up What are the 4 classes of macromolecules? Give an example of each type of macromolecule. Ch. 5 Warm-Up Activity In your family groups, complete #1-5 on Activity 4/5.1: “How can you identify organic macromolecules?” Warm-Up What are the 4 levels of protein structure? What bonds are formed in each level? Which protein was involved in the curds & whey lab yesterday? Explain what happened to the milk to form the curds and whey. Chapter 5 The Structure and Function of Large Biological Molecules You Must Know The role of dehydration synthesis in the formation of organic compounds and hydrolysis in the digestion of organic compounds. How to recognize the 4 biologically important organic compounds (carbs, lipids, proteins, nucleic acids) by their structural formulas. The cellular functions of all four organic compounds. The 4 structural levels of proteins How proteins reach their final shape (conformation) and the denaturing impact that heat and pH can have on protein structure Monomers Polymers Macromolecules Small organic Used for building blocks of polymers Connects with condensation reaction (dehydration synthesis) Long molecules of monomers With many identical or similar blocks linked by covalent bonds Giant molecules 2 or more polymers bonded together ie. amino acid peptide polypeptide protein smaller larger Dehydration Synthesis (Condensation Reaction) Hydrolysis Make polymers Breakdown polymers Monomers Polymers Polymers Monomers A + B AB AB A + B + H2O + + H2O + Dehydration Synthesis Hydrolysis I. Proteins “Proteios” = first or primary 50% dry weight of cells Contains: C, H, O, N, S Myoglobin protein Protein Functions (+ examples) Enzymes (lactase) Defense (antibodies) | Warm-Up What are the 4 classes of macromolecules?
