Learning Guide: Water and Biomolecules (cont.) Bill Activity #17 To Think About: How do molecules and atoms from the environment build new molecules? 1st Read About: Carbon and the Molecular Diversity of Life Pgs. 58-66 Campbell’s Biology 9th edition (2-sided column notes) Organic chemistry is the study of carbon compounds o Explain the definition of organic chemistry and list the primary elements of living things o Describe how Stanley Miller bring the abiotic synthesis of organic compounds into the context of evolution. Carbon atoms can form diverse molecules by bonding to four other atoms. o Make an electron distribution diagram of carbon. List the number of valence electrons, number of bonds and types of bonds it makes with other elements. o Describe how carbon skeletons may vary (four ways), and explain how this variation contributes to the diversity and complexity of organic molecules. A small number of chemical groups are key to the functioning of biological molecules o Describe how two molecules can be very similar in structure but have very different functions. o Define a functional group. List the functional groups. For each write the formula and sketch their structure (in top purple boxes) 2nd Read About: The Structure and Function of Large Biomolecules Pgs. 68-69 Campbell’s Biology 9th edition (2-sided column notes) Macromolecules are polymers, built from monomers o List the four main classes of important large molecules. Define macromolecule and circle the three classes. o Distinguish between a polymer and a monomer; condensation/dehydration reaction and hydrolysis 3rd Interact: Watch Mr. Andersen’s Polymers video and take notes on it. Explain how the letters of the alphabet are similar to monomers of a polymer. Explain the phrase “you are what you eat” in the context of dehydration synthesis and hydrolysis.
