Editorial Accompanying the rapid increase of knowledge on the extreme importance and vital roles of carbohydrates in living systems, carbohydrate chemistry has made its way from a quite underrated area of natural products research right into the focus of modern organic and bioorganic chemistry within a quarter of a century. Just by flicking through the graphical abstracts of major journals, large numbers of papers on carbohydrate chemistry can be found almost anywhere in the contemporary literature. The complexity and polyfunctionality of carbohydrates as a testing ground for modern organic methodology, carbohydrates as building blocks, carbohydrate related mimetics of natural products as enzyme probes, diagnostics, and therapeutics, carbohydrates in material sciences, all these and many more exciting topics demonstrate this lasting boom in glycosciences. Not many other areas are as rich in complexity, subtle reactivity differences, unusual behaviour of compounds and, as a result, so full of challenges, surprises, and rewards. Consequently, it was a great pleasure to accept the proposal by the Managing Editor of the Austrian journal Chemical Monthly, Prof. Heinz Falk, to compile a representative survey of timely research contributed by international leaders in the field as well as by outstanding young talents. This collection is intended to give evidence for the statements made above as well as to provide informat
