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.

Synthesis and Physical Properties of Liquid Crystals: An Interdisciplinary Experiment  Gerald R. Van Hecke, Kerry K. Karukstis, Hanhan Li, Hansford C. Hendargo, Andrew J. Cosand, and Marja M. Fox
This experiment features an investigative approach designed for the introductory science or engineering major and integrates concepts in the fields of chemistry, biology, and physics. Derived from faculty research interests, this novel experiment gives students the opportunity to draw conclusions from tests performed to illustrate the connection between molecular structure and macroscopic properties. The chemical synthesis of the compounds studied further enhances the connection between molecular structure and macroscopic physical properties. The results of two separate physical measurements, refractometry and absorption spectroscopy, are combined to calculate a microscopic, but very practical, property of chiral nematic liquidsthe pitch of the helix formed in the liquid crystalline phase.
