Steroids and sugars are well-known examples of low molecular-mass organic gelators (LMOGs). Although, they have been used and investigated as naturally occurring molecules for many years, the discovery that some are LMOGs was made serendipitously and only a couple of decades ago. Since that time, chemists have designed many LMOGs and have transformed some of their gels into functional materials. The most important objectives of this chapter are: (1) to present the historical development of the above two series of gelators from the standpoint of the relationship between their molecular structures and their aggregate structures in gels and (2) to indicate some of the functions and applications of these gelators that arise, in part, because of the biocompatibility of sugars and steroids.
