The net effect is decarbonylation, cyclization and stereoisomerization which are linked to the structure of the carbohydrate moiety. The main results describe carbohydrates bearing a carbonyl group on the aglycone (Norrish I) or on the ring (Norrish II).

In recent years, as interest in the properties of biological membranes has increased, researchers have used lectins to study the role of the binding of multivalent ligands to the plasms membrane in the induction of specific biological responses. This report will detail the use of lectins to study the structure of the carbohydrate moiety of lymphocyte surface bound H-2 glycoproteins. Furthermore, it will describe a novel lectin-induced perturbation of the metabolism of in vitro cultured fibroblasts which results in the massive accumulation of lysosomes in these cells. This response is greatly reduced in cells which have been transformed by oncogenic viruses. 

The data presented here demonstrate that lectins may be used to explore structural aspects of the carbohydrate moieties of specific cell surface bound antigens. Furthermore, it is suggested that the H-2D antigen possesses differences in the structure of the carbohydrate moieties which may reflect microheterogeneity due to the biosynthesis of only partial structures, differences in the number of sialic acid residues, the relationship of the carbohydrate chains to the specific antigenic determinants and/or major structural differences of the carbohydrate chains on different H—2D antigens.

In recent years the structures of the carbohydrate moieties of some additional gly coalkaloids have been established by similar methods. Thus, the trisaccharide of a-solasonine 207 , see 85) and of a-solamarine... 

A review of complex carbohydrates, which includes a discussion of the structures, isolation, biosynthesis, and functions of glycoproteins, glycosaminoglycans, and blood-group substances, has appeared. The structures of the carbohydrate moieties found in glycoproteins from such diverse sources as fungal and mam-rhalian cells have been compared. ...
