Quantifying Protein–Glycan Interactions Using Native Mass Spectrometry

Mass Spectrometry Reviews, Volume 45, Issue 4, Page 800-828, July/August 2026.
ABSTRACT Interactions between glycan‐binding proteins (GBPs) and carbohydrates (glycans) are essential to many biological processes relevant to human health and disease. For most GBPs, however, their glycan interactome—the repertoire of glycans recognized and their specificities—is poorly defined.

Advancements in Mass Spectrometry‐Based Glycomics in Food and Nutritional Science

Mass Spectrometry Reviews, Volume 45, Issue 4, Page 829-850, July/August 2026.
ABSTRACT This review highlights advancements in mass spectrometry (MS)‐based glycomics in food and nutritional science. Carbohydrates, which are vital for human health, exhibit complex structures, making their analysis challenging. MS has become an indispensable tool for elucidating the structures of carbohydrates, including glycans, through soft ...

External Organic Nitrogen Supply by Atmospheric Aerosols is Important Over the Northwest Pacific Ocean

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Aerosol organic nitrogen (AON) is an important fraction of atmospheric N deposition over the open ocean. However, it is unclear how much of the AON is of external origin or internally recycled from the ocean. Here, we quantified AON over the Northwest Pacific Ocean using a newly developed Aerosol Nitrogen Analyzer and investigated its chemical

Sulfated Seaweed Polysaccharides

2021
Mankind has used natural resources for many different applications, from food and clothes to drugs, but only recently is giving the due attention to the need for a responsible management of these resources toward sustainability. One of the approaches is to take the most out of its resources, addressing the several components of natural resources, which

Sulfation of Polysaccharides using Monomethyl Sulfate

Journal of Carbohydrate Chemistry, 2000
ABSTRACT The polysaccharides, curdlan, starch and dextran were sulfated when heated in DMSO with sodium methyl sulfate and a catalytic amount of H2SO4 or with pyridinium methyl sulfate. Use of diminished pressure and anhydrous CaSO4 as a desiccant improved the degree of sulfation and recovery.

Secretion of Sulfated Polysaccharides by the Gastric Mucosa

Digestion, 2009
Presence of chondroitin-4-sulfate has been demonstrated in the gastric fundic juice of the dog. It is secreted by the chief peptic cells. Chondroitin sulfate-like material was also observed in the pyloric cells of the same animal. In the dog, chondroitin-4- sulfate secretion by the fundus is increased during cholinergic stimulation but not during ...

Antioxidant activities of sulfated pumpkin polysaccharides

International Journal of Biological Macromolecules, 2019
Pumpkin polysaccharide was extracted by hot water extraction method. It was modified with chlorosulfonic acid-pyridine to obtain sulfated pumpkin polysaccharides (SP1, SP2) with different degrees of substitution, which was 0.35 and 0.65, respectively.

A Sulfated Polysaccharide Produced by an Arthrobacter Species

The Journal of Biochemistry, 1982
A new sulfated polysaccharide was isolated from the culture supernatant of a strain of Arthrobacter sp. The polysaccharide purified with quaternary ammonium salts consists of D-galactose, D-glucose, sulfate, phosphorus, glucosamine, muramic acid, alanine, glutamic acid, glycine, and LL-diaminopimelic acid in a molar ratio of 56 : 9.0 : 68 : 6.4 : 2.0 :
