We have characterized the structure of a sulfated d-galactan from the red algae Botryocladia occidentalis. The following repeating structure (-4-alpha-d-Galp-1-->3-beta-d-Galp-1-->) was found for(More)
Marine red algae are an abundant source of sulfated galactans with potent anticoagulant activity. However, the specific structural motifs that confer biological activity remain to be elucidated. We(More)
O-linked oligosaccharide groups ranging from di- to hexasaccharide were beta-eliminated by mild alkaline treatment under reducting conditions from the peptidogalactomannan of Aspergillus fumigatus(More)
The egg jelly coats of sea urchins contains sulfated polysaccharides responsible for inducing the sperm acrosome reaction which is an obligatory event for sperm binding to, and fusion with, the egg.(More)
