Colorimetric differentiation of hexosamines
Analytical Biochemistry, 1967Abstract A colorimetric method is introduced to differentiate glucosamine, galactosamine, and mannosamine. Direct evaluation of galactosamine in mixture with glucosamine was possible since galactosamine was essentially the only component responsible for the color of the reaction; the influence of glucosamine on the intensity of the color was ...

An automated method for the determination of hexosamines
Analytical Biochemistry, 1965Abstract 1. 1. An automated method is described which can be used for the determination of glucosamine, galactosamine, mannosamine, and muramic acid. 2. 2. Under the reaction conditions of the method, the relative amounts of color produced by the hexosamines at 530 mμ were: glucosamine, 100%; galactosamine, 75%; mannosamine, 48%; and muramic ...

Hexosamines and Insulin Resistance
Diabetes, 1996Glucose is an important regulator of cell growth and metabolism. Thus, it is likely that some of the adverse effects of hyperglycemia are reflections of normal regulation by abnormal concentrations of glucose. How the cell senses glucose, however, is still incompletely understood.

Urinary hexosamine and acetyl-hexosamine excretion in human acetylator phenotypes
Clinica Chimica Acta, 1967Abstract Human subjects are divisible into two clearly defined phenotypes by their capacity to acetylate sulfamethazine. The biochemical basis of this polymorphism lies in the possession of high N-acetyltransferase activity in the liver and intestinal mucosa of rapid acetylators as compared with slow acetylators.

Hexosamine in Bombyx mori Silk
Nature, 1965CONSTITUENTS other than protein in Bombyx mori silk have received little attention1. The significant amounts of hexosamine found in hair and wool2 prompted this study to quantitate and to identify the amino-sugars in B. mori silk.

Interference of hexosamines in the Lowry reaction
Analytical Biochemistry, 1971Abstract Glucosamine and galactosamine react with the reagents in the Lowry test for protein and give a similar, though not identical, blue-colored product. When present in solution with albumin, they give erroneously high values in the Lowry reaction and thus interfer with protein determination.

The hexosamine content of leaves
Canadian Journal of Botany, 1974Leaves of 20 species contained both polymer-bound and 80%-acetone-soluble forms of hexosamine. Similar amounts of polymer-bound hexosamine (about 1.9 μg/mg protein) were found in all the leaves, suggesting that it may be an essential element of membrane structure.

The Hexosamine Biosynthesis Pathway
2007Prolonged hyperglycemia is the critical etiological factor in the development of the microvascular complications of diabetes including diabetic nephropathy (1, 2). The tissues subject to these complications appear to be susceptible by virtue of abundant expression of cell surface facilitative glucose transporters resulting in the transport of glucose ...
