The composition of cell walls varies depending on the function of the tissue and the species of plant. Primary cell walls surround expanding cells in young tissues, whereas thickened secondary cell ...

In Gram-negative bacteria, which include some of the most devastating human pathogens, just two mechanisms for the export of polysaccharides have been identified so far. Now a research team has ...

Polysaccharides—long chains of simple sugars—play central roles in biological systems, including supporting cell structure, storing chemical energy, and regulating cell recognition. But synthesizing ...

Hooking sugar molecules together to make strings called glycans—also known as oligosaccharides and polysaccharides—is one of synthetic chemistry’s most bedeviling challenges. Carbohydrates are ...

Conjugate vaccines are composed of bacterial polysaccharide antigens covalently linked to protein carriers, enabling T cell-dependent immune responses that induce high-affinity antibodies and ...

Polysaccharides are made by polymerizing more than 10 monosaccharide molecules through glycosidic bonds. The molecular weight of polysaccharides is relatively large, usually consisting of hundreds or ...

Albizzia julibrissin is a widely distributed plant in China. Its dried stem bark has been used in traditional oriental medicine to treat insomnia, diuresis, sthenia, ascaricide, and confusion.
