Transdermal Permeability of N-Acetyl-D-Glucosamine

Pharmaceutical Development and Technology, 2007
Transdermal permeation of N-acetyl-D-glucosamine (NAG), a metabolite of glucosamine was examined. Glucosamine salts are nutraceuticals used in the oral treatment of osteoarthritis. Sparse information is available regarding glucosamine and NAG transdermal or percutaneous transport and absorption.

Polycondensation of N-acetyl-D-glucosamine and structure of poly (N-acetyl-D-glucosamine)

Polymer, 1977
Abstract N- Acetyl- d -glucosamine was polymerized by the action of phosphorus in dimethyl sulphoxide or poly(phosphoric acid ester) in dimethylformamide. The structure of the synthetic poly ( N- acetyl- d -glucosamine ) was determined by chemical methods. Polymers obtained from the phosphorus pentoxide/dimethyl sulphoxide system were

Chromatography of methyl ethers of d-glucosamine

Analytical Biochemistry, 1971
Abstract Identification of methyl ethers obtained by methylation and subsequent hydrolysis is a powerful technique for determination of linkage positions in structure studies of complex carbohydrates. Although methyl ethers of neutral sugars have been separated by various chromatographic methods, separation of methyl ethers of 2-amino-2-deoxy- d ...

[117] d-glucosaminic acid dehydrase

1966
Publisher Summary This chapter discusses the determination of D-glucosaminic acid dehydrase. The dehydrase catalyzes the conversion of D-glucosaminic acid to 2-keto-3-deoxy-D-gluconie acid (KDG) and NH 3 . The α-keto acid is measured as its semicarbazone according to the procedure of MacGee and Doudoroff.
