Molecular Models of Natural Products William F. Coleman
This months Featured Molecules focus on natural products and include blattellquinone, a sex pheromone secreted by female German cockroaches to attract males, and (R)-limonene, a secondary metabolite found in citrus fruit peels.

Identification of Secondary Metabolites in Citrus Fruit Using Gas Chromatography and Mass Spectroscopy Jean-Michel Lavoie, Esteban Chornet, and André Pelletier
Using a simple extraction and a gas chromatograph coupled with a mass spectrometer, this protocol allows students in analytical or organic chemistry to quantify and qualify monoterpenes from the peels of limes, grapefruits, and oranges.

Identification of Volatile Flavor Components by Headspace Analysis: A Quick and Easy Experiment for Introducing GC/MS Richard Kjonaas, Jean L. Soller, and Leslee A. McCoy
By placing a piece of chewing gum (Wrigley's) or a crushed piece of hard candy (LifeSavers or Runts) into a vial, followed by GC/MS analysis of a five microliter sample of the headspace, students are able to identify several of the volatile flavoring components which are present.

Hot and Spicy versus Cool and Minty as an Example of Organic Structure-Activity Relationships Doris R. Kimbrough
Structures of substances found in spices and food that we normally associate with "hot" (or spicy) and "cool" (or minty) flavors are presented and discussed. Functional group similarities within the two groups provide an interesting example of the relationship between molecular structure and molecular function.

Monoterpenes: An easily accessible but neglected class of natural products Glidewell, Christopher
The class of products is structurally and spectroscopically straightforward and many in this group are key components of familiar flavors and odors. I.e., extraction of orange peel.
