Improving The Antioxidant Activity of Sodium Alginate from Sargassum sp. by Thermal Heating and Chemical Methods

Jurnal Kelautan Tropis, 2020
The relationship between molecular structure and bioactivity was evaluated for sodium alginates obtained under different degradation treatment (raw alginates, heat-treated, and chemical-treated) from Sargassum sp. This study was conducted to identify the

The Potential of Seaweeds as a Source of Functional Ingredients of Prebiotic and Antioxidant Value [PDF]

, 2019
Two thirds of the world is covered by oceans, whose upper layer is inhabited by algae. This means that there is a large extension to obtain these photoautotrophic organisms.

Daily ingestion of alginate reduces energy intake in free-living subjects [PDF]

, 2008
Sodium alginate is a seaweed-derived fibre that has previously been shown to moderate appetite in models of acute feeding. The mechanisms underlying this effect may include slowed gastric clearance and attenuated uptake from the small intestine. In order

Exploiting Mannuronan C-5 Epimerases in Commercial Alginate Production

Marine Drugs, 2020
Alginates are one of the major polysaccharide constituents of marine brown algae in commercial manufacturing. However, the content and composition of alginates differ according to the distinct parts of these macroalgae and have a direct impact on the ...

Molecular weight and viscosifying power of alginates produced by mutant strains of Azotobacter vinelandii under microaerophilic conditions

Biotechnology Reports, 2020
Alginates are polysaccharides that are of interest in various industrial applications. This is due to the viscosifying properties of alginates, which depends on the weight-average molecular weight. The aim of the present study was to evaluate the changes

Alginate reduces the increased uptake of cholesterol and glucose in overweight male subjects: a pilot study [PDF]

, 2008
Dietary fibers are of particular interest in the prevention and management of obesity and consequent pathologies. Among the proposed mechanisms of action of fiber is the modulation of nutrient uptake from the small intestine.

Characterization of Alginates of Sargassum from the Archipelago of Guadeloupe

Separations
Sargassum is a genus of brown algae that causes a major impact to marine ecosystems. Although accumulation of this invasive seaweed is considered an environmental problem, Sargassum can also be resource of valuable molecules such as alginates.

Alginate supramolecular hydrogels based on viologen and cucurbit[8]uril: Host‐induced caveolae‐mediated endocytosis to white blood cancer cells

View, 2023
The cellular uptake of drug carriers to the cytosol of a specific cell remains challenging, and a non‐classical supramolecular strategy is motivated. Here, we select a model host–guest complex in which a diamino‐viologen (1,1′‐bis(4‐aminophenyl)‐[4,4 ...
