Structures for the ABO(H) Blood Group: Which Textbook Is Correct? John M. Risley
Six textbooks and two Internet sites show different structures for the A, B, and O(H) antigens of the ABO(H) blood group, but none of them are correct. This article emphasizes the correct molecular structures because it is important to distinguish between those carbohydrates that make up the antigens and those that are not part of the antigenic structures.

Our Everyday Cup of Coffee: The Chemistry behind Its Magic Marino Petracco
Coffee beverages are so popular all over the world that there is hardly any need to describe them. But underlying this seemingly commonplace beverage there is a whole realm worth serious scientific study. The complexity of the raw seed matrix, made even more intricate when roasted, requires a deep understanding of its chemical nature. While coffee is not consumed for nutritional purposes, it is appreciated for its taste appeal along with its stimulating effects on mental and physical activity. The attention to quality is of paramount importance to both of these aspects to supply the customers with a pleasant and wholesome product.

Let's Drive "Driving Force" Out of Chemistry Norman C. Craig
"Driving force" is identified as a misleading concept in analyzing spontaneous change. Driving force wrongly suggests that Newtonian mechanics and determinism control and explain spontaneous processes. The usefulness of the competition of ?H versus ?S in discussing chemical change is also questioned. Entropy analyseswhich consider the contributions to the total change in entropyare advocated.

Lipid Extraction and Cholesterol Quantification: A Simple Protocol M. Carmo Barreto
A fast and simple protocol for lipid extraction from egg yolk and walnut is presented. Students learn to extract total lipids from both sources and to assess the quantity of cholesterol in lipid extracts by the LiebermannBuchard method, in a semi-quantitative way. This experiment is easily done in a two-hour lab period, except for the evaporation of lipid extracts to dryness, which proceeds overnight and is weighed by the students the following day

Chocolate: A Marvelous Natural Product of Chemistry Ginger Tannenbaum
This article is a survey of chocolate from tree to table. After a brief introduction to the history of chocolate and how and where it is grown, the manufacturing process is examined, and the chemistry is explored. A bit of the jargon used in the industry is mentioned. Cocoa butter is a significant ingredient in chocolate, and an investigation of it introduces triglycerides, fatty acids, polymorphic behavior, and molecular packing of the fats in chocolate and how they affect the tempering process. There is a brief discussion of chocolate's non-Newtonian behavior and the resulting challenges presented in the manufacturing process.

Consumer Views on Chemical Additives: Are They Natural or Synthetic? A Non-Laboratory-Based Project A. S. Cotterill, D. N. John, and Y. S. Teh
Results of a study demonstrate that consumers are not well informed about identifying natural products but do recognize names to which they have been exposed. Consumers also appreciate that natural compounds can come from a variety of sources and can be synthesized, and that a natural substance is not necessarily good for you or better than a synthetic substance. However, despite this knowledge, consumers do prefer products that contain natural or natural-sounding additives.

Anthocyanins: Model Compounds for Learning about More than pH Robert Curtright, James A. Rynearson, and John Markwell
In recent years it has become common to use anthocyanins as pH indicators.

This article focuses on the use of anthocyanins in chromatography and hydrolysis.
