Heterofucans from the Brown Seaweed Canistrocarpus cervicornis with Anticoagulant and Antioxidant Activities

Marine Drugs, 2011
Fucan is a term used to denominate a family of sulfated polysaccharides rich in sulfated L-fucose. We extracted six fucans from Canistrocarpus cervicornis by proteolytic digestion followed by sequential acetone precipitation.

Photopolarization of Fucus zygotes is determined by time sensitive vectorial addition of environmental cues during axis amplification [PDF]

, 2015
Fucoid zygotes have been extensively used to study cell polarization and asymmetrical cell division. Fertilized eggs are responsive to different environmental cues (e.g., light, gravity) for a long period before the polarity is fixed and the cells ...

Evaluation of Sulfated Polysaccharides from the Brown Seaweed Dictyopteris Justii as Antioxidant Agents and as Inhibitors of the Formation of Calcium Oxalate Crystals

Molecules, 2013
Oxalate crystals and other types of crystals are the cause of urolithiasis, and these are related to oxidative stress. The search for new compounds with antioxidant qualities and inhibitors of these crystal formations is therefore necessary.

Inhibitory effects of fucan sulfates on enzymatic hydrolysis of starch

LWT - Food Science and Technology, 2011
Abstract The effect of fucoidan and its oversulfated derivative on starch digestibility was investigated by determining the enzymatic reaction kinetics and their inhibitory activity against α-amylase and amyloglucosidase. After the α-amylase hydrolysis, the produced reducing sugars of the buckwheat starch (BW, 2.0–3.0 g/100 mL) and those of the ...
