Preparation of <i>N</i>‑Linked-Type GlcNAc Monomers for Glycopolymers and Binding Specificity for Lectin
Glycomonomers having N-glycosidic linkages
were
prepared from a known glycosyl amine, N-acetyl-d-glucosamine (GlcNAc). Radical polymerization of the glycomonomers
gave a series of glycopolymers displaying various sugar densities,
which were models of the core structure of Asn-linked-type glycoproteins.
In addition, fluorometric analyses of wheat germ agglutinin (WGA)
against the glycopolymers were carried out, and the results showed
unique binding specificities on the basis of flexibility of sugar
moieties

Physicochemical features of rivers and lakes in pantanal wetland
The Pantanal is one of the largest wetland in the world, and its located almost in the central part of South America. Preliminary studies on the chemical features of waters were carried out in July, 1983 in Rio Paraguai and its tributaries in southern Pantanal, and in January, 1986 for some lakes near Porto Jofre and a river in northern Pantanal. The former showed an extremely oligotrophic character and the latter a eutrophic character, while the nitrogen seemed to be the limiting nutrient rather than phosphorus in both waters. The oxygen deficiency in water seemed rather common throughout the area studied in spite of the difference in water temperature and the organic matter contents.Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq
