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.

Acetal Protecting Groups in the Organic Laboratory: Synthesis of Methyl 4,6-O-Benzylidene-α-D-Glucopyranoside  Alexei V. Demchenko, Papapida Pornsuriyasak, and Cristina De Meo
The synthesis of methyl 4,6-O-benzylidene-a-D-glucopyranoside provides an opportunity to synthesize a cyclic acetal; stereoselectively introduce a chirality center; and learn extraction, evaporation, precipitation, optical rotation, melting point measurement, thin-layer chromatography, IR-spectroscopy, mass spectrometry, and various NMR techniques.

Glycosyltransferases A and B: Four Critical Amino Acids Determine Blood Type  Natisha L. Rose, Monica M. Palcic, and Stephen V. Evans
Human A, B, and O blood type is determined by the presence or absence of distinct carbohydrate structures on red blood cells. In this review the chemistry of the blood group ABO system and the role of glycosyltransferase A, glycosyltransferase B, and the four amino acids critical to determining blood group status are discussed.

Protecting Groups in Carbohydrate Chemistry  Sigthór Pétursson
The most important protecting groups in carbohydrate chemistry are reviewed. The paper is aimed at those beginning to specialize in synthetic carbohydrate chemistry and at teachers with other specialties who wish to go beyond the content of general organic chemistry textbooks.

The Use of a "Qual" Centrifuge for Greatly Simplifying and Speeding the Study of Milk  Quentin R. Petersen
Laboratory study of the constituents of milk is almost always slowed by difficult separation of relatively large amounts of curd and whey by filtration. In the two-and-one-half hour experiment described, only 5 mL of skim milk is used and the curd is separated from the whey by using a simple "qual" centrifuge.
