Trust Our Marine Mannoglucan Characterization Service for Cutting-edge Analysis and Innovative Insights
At CD BioGlyco, we are deeply involved in the field of marine biotechnology and are committed to providing cutting-edge Marine Carbohydrate Characterization Services to global clients. As an important branch of this comprehensive service framework, we specifically provide Marine Plant Polysaccharide Characterization Services for marine plant resources, aiming to deeply analyze the complex structure and unique functions of these plant polysaccharides from the vast ocean. In this special service, mannoglucan characterization service is one of the key services, which focuses on comprehensive and accurate characterization analysis of marine mannoglucan, from molecular structure to biological functional characteristics.

Monosaccharide Composition Analysis
- High-performance liquid chromatography (HPLC): We utilize HPLC to determine the precise monosaccharide composition of the marine mannoglucans. This process involves hydrolyzing the polysaccharides into their monosaccharide components, which are then separated and quantified.
- Gas chromatography-mass spectrometry (GC-MS): By transforming the monosaccharides into volatile derivatives, GC-MS provides a highly sensitive method to identify and quantify the individual glycans present in the mannoglucan samples.
Molecular Weight Determination
- Size exclusion chromatography (SEC): SEC is employed to determine the molecular weight distribution of marine mannoglucans. This technique separates molecules based on size, providing vital information about the polymer distribution.
- Multi-angle laser light scattering (MALLS): When coupled with SEC, MALLS offers an accurate measure of the molecular weight and radius of gyration, leading to a comprehensive understanding of the polymer structure.
Structural Analysis
- Nuclear magnetic resonance (NMR) spectroscopy: NMR is pivotal in elucidating the detailed structural features of mannoglucans, including linkage types and anomeric configurations. This technique provides a molecular-level insight into the arrangement of monosaccharides.
- Fourier-transform infrared (FTIR) spectroscopy: FTIR is used to characterize functional groups and identify characteristic absorption bands related to specific bonds within the mannoglucan structure.
- Matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrometry: This technique allows us to analyze the mass-to-charge ratio of ionized polymer fragments, offering insights into the repeat units and possible modifications in the mannoglucans.
Rheological Property Assessment
- Viscometry: We assess the viscosity of marine mannoglucan solutions to understand their flow behaviors, which is crucial for applications where gelation and thickening properties are essential.
- Dynamic mechanical analysis (DMA): DMA offers insights into the mechanical properties of mannoglucan-based hydrogels, such as their elasticity and stress resistance.
Functional Property Assessment
- Bioactivity assays: We conduct in vitro and in vivo assays to evaluate the specific biological activities of marine mannoglucans, including their anti-inflammatory, antiviral, and immunomodulatory effects.
- Thermal analysis: Techniques like differential scanning calorimetry (DSC) are used to assess thermal stability and transitions, providing critical data for processing and application development.

Results: The authors aimed to explore the potential of Bullacta exarata in medical applications by isolating and purifying a mannoglucan, designated as BEPS-IB, from the foot muscle of B. exarata following papain digestion. Chemical composition analysis revealed that BEPS-IB primarily comprised glucose and mannose in a molar ratio of 1:0.52, with an approximate molecular weight of 94 kDa. Methylation analysis was used to determine the linkage information, while IR and 2D NMR confirmed the anomeric configuration and chain linkage. The findings showed that BEPS-IB consisted of a Glcp6Manp heptasaccharide repeating unit in the backbone, with occasional mannose branch chains (14%) attached to the backbone mannose. Further antioxidant assays demonstrated that BEPS-IB exhibited positive antioxidant activity, effectively scavenging superoxide radicals and exhibiting reducing power.
