D-Mannose-specific interaction between xanthan and D-galacto-D-mannan

The Occurrence of D-mannose in Seaweed and the Separation of L-fucose and D-mannose.*

The wide-spread occurrence of mannans and fucosans in nature makes it not improbable that some of these vegetable gums may in fact consist in part at least of fuco-mannans. In general the isolation and identification of two or more sugars from a mixture is often fraught with experimental difficulties, particularly if the material is available only in small amounts. Any simple procedure applicab...

BUPROPION-INDUCE D CLIMBING THROU GH D -1 AND D-2 DOPAMINE RECEPTOR ACTIVATION

Intraperitoneal (IP) injection of bupropion (3,6, amine (4,16 mg kg•') induced dose-dependent climbing in mice. The climbing response induced by both drugs were decreased in animals pretreated either with the 0-1 antagonist SCH 233<)0 or the 0-2 antagonist sulpiride. The α-adrenoceptor blocker phenoxybenzamine decreased the climbing induced by both bupropion and amphetamine, but the β-ad...

Enzymatic assay of D-mannose in serum.

We describe a new and improved enzymatic assay for determining the concentration of D-mannose in sera. Serum D-glucose is selectively converted to glucose-6 phosphate with the highly specific thermostable glucokinase (EC 2.7.1.2) from Bacillus stearothermophilus. The anionic reaction products and excess substrates are removed by a rapid and simple anion-exchange chromatography step in microcent...
