Liquid Crystals, 1994
Abstract New liquid crystalline compounds have been prepared from glucosamine and 6-amino-6-deoxy-hexopyranoses. The monoalkylated carbohydrates show smectic phases. The influence of the amino group on the clearing temperatures is minor. The salts of the cyclic amines can form smectic or discotic mesophases.

Phenyloxazoline derivatives of amino-sugars
Journal of the Chemical Society, Perkin Transactions 1, 1972The preparation and borohydride reduction of 2,3-dideoxy-5,6-O-isopropylidene-2′-phenyl-D-allofuranoso-[2,3-d]-Δ2′-oxazoline (XXI) are described. The reduction product was a derivative of 2-amino-2-deoxy-D-allitol, indicating that no isomerisation of the sugar system in compound (XXI) had occurred during its formation and reduction.

Amino sugar metabolism in erythrocytes
Biochimica et Biophysica Acta (BBA) - General Subjects, 1968Abstract The ability of rabbit erythrocytes to synthesize glucosamine and convert it to UDP-N-acetylglucosamine (UDP-GlcNAc) has been measured in mature erythrocytes, in reticulocytes, and in the immature bone marrow erythroid cells. The cells were incubated with either [14C]fructose which can be converted via fructose 6-phosphate (Fru-6-P) to ...

Fluorometric analysis of amino sugars and derivatized neutral sugars
Analytical Biochemistry, 1982Abstract A rapid and sensitive procedure for the analysis of neutral and amino sugars is presented. Neutral sugars are separated after conversion to the corresponding glycamines, while the amino sugars are analyzed without modification, using an automatic amino acid analyzer and fluorometric detection.

Cell-Wall Amino-Acids and Amino-Sugars
Nature, 1957STUDIES of the chemistry of cell walls of many Gram-positive bacteria have established that they possess distinctive properties; indeed, a number of the uncommon constituents of bacterial cells have been found to be localized in the walls, for example, αɛ-diaminopimelic acid, D-isomers of amino-acids, and the sugars D-arabinose and rhamnose1–3.

Heterocyclic amino sugar derivatives
Carbohydrate Research, 1973Abstract Benzyl 2-deoxy-α- d -gulopyranosido[2,3:4′,5′]-2′-oxazolidinone ( 10 ) was synthesized from benzyl 3- O -acetyl-2-[(benzyloxycarbonyl)amino]-2-deoxy-α- d -glucopyranoside ( 1 ) via the 4- O -methylsulfonyl-6- O -trityl derivative and 3,4-anhydro-α- d -galactopyranoside derivatives.
