A-L-gulopyranosyluronic acid

Alginic acid is a copolymer of P-D-mannopyranosyluronic acid (1) and a-L-gulopyranosyluronic acid (2) units linked 1— 4, with no detectable... [Pg.295]

The term alginate refers to the salt forms of alginic acid [9005-32-7] a copolymer of D-mannopyranosyluronic acid [56687-62-8] (1) and L-gulopyranosyluronic acid [56688-68-7] (2) residues. [Pg.295]

Uronic acid derivatives are also known among the guanosine 5 -pyrophosphate esters. A mixture of the a-D-mannopyranosyluronic acid ester (20) and, presumably, the /J-L-gulopyranosyluronic acid ester (21) was isolated from the brown alga Fucus gardneri,88 The conversion of the uronic acid in the ester 20 into D-mannitol, and that... [Pg.320]
