Basic Key Concepts
After completing the readings and practice exercises, students should be able to: Define the biologically relevant interactions (bonds) between molecules. List functional groups commonly found in biological molecules. List from memory the electronegativity of carbon, nitrogen, oxygen and hydrogen. Summarize how polymers are made and broken down and how water participates in these reactions. List the different kinds of biological macromolecules and their monomers. Describe the structure and functions of:
Summarize the different forms and functions of complex carbohydrates. Describe the possible levels of protein structure.
Summarize the fundamental property of all lipids.
Illustrate the structure of triglycerides and phospholipids.
Advanced Key Concepts
After the biomolecules lectures, students should be able to: Predict what type of bond would be formed using electronegativity information. Describe the relationship between functional groups and the molecules they are part of. Given amino acid structure, predict the properties of amino acids using information from the structure of the R group. Summarize why and where carbohydrates are commonly combined with other macromolecules. Compare and contrast the structure and functions of DNA and RNA. Describe the four types of lipids.
Summarize and predict commonalities and differences in lipid structure and function Describe how man-made fats are different from those found in nature and what their properties are. Describe nonliving infectious agents and summarize how they operate to make you sick. Be able to define, identify, and (where appropriate) name the function of the following: Ionic bond
Polar covalent bond
