During development, the epithelial component of the lung goes through a complex orderly process of branching, following strict patterns of space and time. Proteoglycans, glycosaminoglycans and growth factors are fundamental components of the extracellular matrix and perform a key role in differentiative processes. The embryonic chick lung shows a specific glycosaminoglycan composition at differ...

The monosaccharide u&s most commonly found in glycoproteins are n-galactose, n-mannose, M-acetyl-u-glucosamine, sialic acid, and L-fucose. The hydrolysis of individual carbohydrate units by specific glycosidases is an excellent tool for studying the sequenbial arrangement and anomeric configuration of the carbohydrate units in the glycoproteins. In previous studies, cr-mannosidase (cr-u-mannosi...

Winemaking is a complex process involving the interaction of different microbes. The two main groups of microorganisms involved are yeasts and bacteria. The yeasts present in spontaneous fermentation may be divided into two groups: the Saccharomyces yeasts, particularly S. cerevisiae; and the non-Saccharomyces yeasts, which include members of the genera Rhodotorula, Pichia, Candida, Debaryomyce...

Dihydroxylation of (R,S) or (S,S)-2,6-disubstituted dehydropiperidines enantioselectively obtained from stannylated precursors allows a versatile preparation 2-deoxyiminosugar C-glycosides which have been evaluated as glycosidases inhibitors.

The distribution of the activity of seven acid glycosidases in the reproductive organs of the pheasant (Phasianus colchicus) was studied. The study was carried out on seven mature birds at the age of 11 months during the reproductive season (May). Significant (p<0.01) differences in acid glycosidase activity dependent on enzyme origin were observed. Generally, the highest activity of acid glyco...
