Further study of the glycolipids from marine invertebrates, along with investigation of other classes of compounds, may well help in creating the foundation for a chemical taxonomy of these animals. 

One of the most widely studied chemotaxonomic characters in insects has been cutic-ular hydrocarbons (CHCs). The earliest descriptive papers on CHCs were by Jackson (1970), Jackson and Bayer (1970), Jackson and Blomquist (1976), Lockey (1976), and Lange et al. (1989). Carlson and collaborators (Carlson and Service 1979, 1980 Carlson et al., 1978 Carlson, 1988) were the first to recognize the special role of CHCs in chemical taxonomy. Since then, numerous reviews have devoted sections to CHCs (Lockey, 1980, 1988 Howard and Blomquist, 1982,2005 Blomquist and Dillwith, 1985 Blomquist et al., 1987 Kaib et al., 1991 Singer, 1998 Howard, 1993). Since the introduction of molecular techniques, the number of insect chemotaxonomy papers about hydrocarbons has dropped, but there are still many submissions and publications. Explanations for this continued interest in insect CHCs include not only their importance as chemical cues in recognition processes, but also the fact that insects are excellent bioindicators of nature conservation, and inversely, pests to control. 

At this time it should be noted that in the process of creating such a unified nomenclature, there is the need to re-examine and occasionally to reformulate the geometrical foundations upon which the present understanding of chemistry is based. This sometimes means viewing from different perspectives some of the "elementary" physics that underlie chemical taxonomy. 

Their URI-fication of the InChl, and the URI-fication by the INFO registry, are not identical, so there is some standardization yet to be achieved. Likewise, their chemical taxonomy and ChEBI are not yet interoperable.

While the potential value of plant secondary metabolites to taxonomy has been recognized for nearly 200 years (Candolle, 1804 Abbott, 1886), their practical application has been restricted to this century and predominantly to the past 45 years. The first extensive advocacy of chemical taxonomy came...
