Abstract
Carbohydrates, in the form of glycoconjugates, have recently been shown to control a wide range of cellular processes. Accordingly, students interested in the study of organic chemistry and biomedical sciences should be exposed to carbohydrate chemistry. To this end, we have developed a sequence of experiments that leads the student from the derivatization of naturally occurring D-glucose through to the formation of simple alkyl and aryl glycosides, and in doing so this experiment provides a comprehensive overview of the fundamentals of glycoside synthesis. These experiments focus on the control of stereochemistry at the anomeric center and NMR spectroscopy for the structural elucidation of products.
Supplement
Handouts from the student laboratory manual; Notes for the teaching assistants; NMR spectra (1D and 2D)

 Caution! 
Experiments, laboratory exercises, lecture demonstrations, and other descriptions of the use of chemicals, apparatus, instruments, computers, and computer interfaces are presented in the Journal of Chemical Education as illustrative of new or improved ideas or concepts in chemistry instruction and are directed at qualified teachers. Although every effort is made to assure and encourage safe practices and safe use of chemicals, the Journal of Chemical Education cannot assume responsibility for uses made of its published materials. Many chemicals are hazardous. Precautions for the safe use of hazardous chemicals and directions for their proper disposal are described in the Material Safety Data Sheets and on the labels. We strongly urge all those planning to use materials from our pages to make choices and to develop procedures for laboratory and classroom safety in accordance with local needs and situations.
