Information about the biosynthesis of the carbohydrate portions or glycans of glycoproteins is presented. The teaching of glycosylation can be used to develop and emphasize many general aspects of biosynthesis, in addition to explaining specific biochemical and molecular biological features associated with producing the oligosaccharide portions of…

Three methods are given for the synthesis of N-4 substituted sulfonamides. An example elucidates the procedures involved in one of the methods. The example is intended as a model for students. (SA)

Described is an experiment in which students are able to synthesize an unnatural compound having the odor and flavor of coconuts. Laboratory equipment, procedures, and analysis of the product are discussed. (CW)

Discusses the various ways that textbooks treat the energetics of protein synthesis. Offers an approach to explaining the phenomenon by emphasizing the ordering aspects of the process. Describes the participation of compounds such as ATP and GTP in the ordering process. (TW)
