Far Ultraviolet Circular Dichroism of Oligosaccharides
Although many biological polymers possess both structural and information carrying functions, molecules such as DNA and messenger RNA are usually associated with the latter function while collagen and bacterial cell wall polysaccharides are thought of as mainly structural. That such a division should not be made along strictly chemical lines is shown by the example of ribosomal RNA, whose role is structural, and by the protein hormones which carry information between cells of higher organisms. Although a purely structural and metabolic function has generally been envisioned for the carbohydrate biopolymers, it is instructive to consider what, if any, informational role might be played by the sugars.
