Identification of amino sugars by paper chromatography
Pierre Stoffyn,Roger W. Jeanloz +1 more
TL;DR: A method is described which permits separation, identification, and determination of glucosamine and galactosamine by paper chromatography by detecting small amounts of one of the amino sugars in the presence of more than 100 μg.
Book ChapterDOI
Structure and biological activity of heparin
TL;DR: The structure and biological activity of heparin are described, being an alternating copolymer of a hexosamine and an alduronic acid, and the repeating disaccharide units constituting the largest fraction of the most common GAG are elaborated in the chapter.

Determination of 2-deoxy-2-sulfoaminohexose content of mucopolysaccharides.
David Lagunoff,G. Warren +1 more
TL;DR: Of the substances tested for interference, only DNA is sufficiently chromogenic to interfere significantly with the determination of N-sulfated hexosamine under most circumstances.
Journal ArticleDOI
Recent trends in the synthesis of O-glycosides of 2-amino-2-deoxysugars.
TL;DR: The discovery of new methods for stereoselective glycoside synthesis and convergent oligosaccharide assembly has been critical for the area of glycosciences and the current standing in the field is evaluated.
Journal ArticleDOI
Infrared absorption and raman scattering of sulfate groups of heparin and related glycosaminoglycans in aqueous solution
TL;DR: In this article, the i.r. spectra for aqueous solutions of sulfated glycosaminoglycans and model compounds in the transmittance window region of the solvent (1400-950 cm −1 ) are dominated by the strong and complex absorption centered at ∼1230 cm − 1 and associated with the antisymmetric stretching vibrations of the SO groups.

TL;DR: It is recommended that the proteases described in this paper shall be considered identical until evidence to the contrary is adduced, and that they be called leaf proteases, adding where necessary the name of the plant.
