α-D-mannopyranose

Methyl α-D-mannopyranoside (α-Methyl-D-mannoside) is a methyl glycoside derivative and conformational stabilizer of α-D-mannopyranose. The glycosidic bond conformation of Methyl α-D-mannopyranoside is significantly affected by the environment. In aqueous solution, Methyl α-D-mannopyranoside stabilizes into a trans conformation via intermolecular hydrogen bonds; in the gas phase, however, steric interactions drive Methyl α-D-mannopyranoside to prefer a clockwise gauche conformation. Methyl α-D-mannopyranoside also serves as a major component of secondary cell wall polymers in some bacteria and an active precursor site for virus-targeted glycoproteins. Methyl α-D-mannopyranoside acts as an acceptor substrate for alternansucrase, mediating the transfer of D-glucopyranosyl groups to generate a variety of glycosylated oligosaccharide products, with methyl α-D-glucopyranosyl-(1→6)-α-D-mannopyranoside as the main component. Methyl α-D-mannopyranoside is applicable to studies on bacterial pathogenic mechanisms associated with mannose-specific fimbrial lectins .

1,3,4,6-Tetra-O-acetyl-2-azido-2-deoxy-α-D-mannopyranose is a biochemical reagent that can be used as a biological material or organic compound for life science related research. 1,3,4,6-Tetra-O-acetyl-2-azido-2-deoxy-α-D-mannopyranose is a click chemistry reagent, it contains an Azide group and can undergo copper-catalyzed azide-alkyne cycloaddition reaction (CuAAc) with molecules containing Alkyne groups. It can also undergo strain-promoted alkyne-azide cycloaddition (SPAAC) reactions with molecules containing DBCO or BCN groups.

3-O-α-D-Mannopyranosyl-α-D-mannopyranose xylosylphosphotransferase (EC 2.7.8.32) is a transferase that can convert 3-alpha-D-mannopyranosyl-alpha-D-mannopyranose and UDP-alpha-D-xylose into 3-O-(6-O-alpha-D-xylosylphospho-alpha-D-mannopyranosyl)-alpha-D-mannopyranose, UMP and H ⁺.
