Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

Mass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

Dielectric Relaxation, Water Sorption Thermodynamics, and Humidity‐Sensing Mechanisms of Compressed Ulva Biomass Pellets

Applied Research, Volume 5, Issue 6, December 2026.
This study investigates the moisture sorption thermodynamics, dielectric relaxation behavior, and humidity‐sensing performance of compressed Ulva biomass pellets. The findings demonstrate that sustainable macroalgal pellets provide low hysteresis (~1.63%) and wide‐range sensitivity for green environmental diagnostics.

Complex sulfated galactans from hot water extracts of red seaweed Asparagopsis taxiformis comprise carrageenan and agaran structures

, 2023
Hot water extraction from the red seaweed Asparagopsis taxiformis yielded three extracts which showed sulfated galactans with a D:L-galactose ratio non consistent with carrageenan or agaran backbones.

Antithrombotics from the Sea: Polysaccharides and Beyond

Marine Drugs, 2019
Marine organisms exhibit some advantages as a renewable source of potential drugs, far beyond chemotherapics. Particularly, the number of marine natural products with antithrombotic activity has increased in the last few years, and reports show a wide ...

Isolation, Structural Elucidation, and Anti‐Melanogenic Activity of a Novel Pectic Polysaccharide From Alhagi camelorum Fisch

Chemistry &Biodiversity, Volume 23, Issue 11, November 2026.
Polysaccharide extraction from Alhagi camelorum Fisch. was optimized, yielding ACP‐II‐1, a novel GalA‐rich, HG‐dominant pectin (26.145 kDa) containing branched RG‐I domains. ACP‐II‐1 reduced melanogenesis in forskolin‐stimulated B16F10 cells and a zebrafish model.

A Novel κ-Carrageenase from Marine Bacterium Rhodopirellula sallentina SM41: Heterologous Expression, Biochemical Characterization and Salt-Tolerance Mechanism Investigation

Marine Drugs, 2022
κ-carrageenases are members of the glycoside hydrolase family 16 (GH16) that hydrolyze sulfated galactans in red algae, known as κ-carrageenans. In this study, a novel κ-carrageenase gene from the marine bacterium Rhodopirellula sallentina SM41 (RsCgk ...

Structural Characterization and Immunomodulatory Activity of a Polysaccharide From Ipomoea batatas L. Vine: Activation of Macrophage

Food Science &Nutrition, Volume 14, Issue 11, November 2026.
IBPS‐3A, an acidic heteropolysaccharide purified from sweet potato vines, was structurally characterized to possess a backbone consisting of →4)‐α‐D‐GalpA‐(1→ and →2,4)‐α‐L‐Rhap‐(1→ linkages with arabinogalactan side chains. Further investigation revealed that IBPS‐3A induced M1 polarization in RAW264.7 macrophages, stimulating the secretion of TNF‐α ...

The Cell Wall of Seagrasses: Fascinating, Peculiar and a Blank Canvas for Future Research

Frontiers in Plant Science, 2020
Seegrasses are a polyphyletic group of angiosperm plants, which evolved from early monocotyledonous land plants and returned to the marine environment around 140 million years ago.

Systematic Evaluation of Cyanidioschyzon merolae Across Photobioreactor Systems: Linking Reactor Design to Biomass Production and Biochemical Composition

Microbial Biotechnology, Volume 19, Issue 11, November 2026.
Systematic comparison of cultivation platforms revealed that photobioreactor design strongly influences growth, biomass productivity, and biochemical composition of the extremophilic red algae Cyanidioschyzon merolae. An internal‐illuminated photobioreactor achieved the highest biomass yields and starch levels, highlighting C.

Dual Effects of Sulfated D-galactans from the Red Algae Botryocladia occidentalis Preventing Thrombosis and Inducing Platelet Aggregation

, 2001
SummarySulfated D-galactans occur on the red algae Botryocladia occidentalis as three fractions that differ in their sulfate content. Fractions F2 and F3 are potent anticoagulants.
