Glycans are compounds composed of many monosaccharides connected by glycosidic bonds or the carbohydrate part of glycoconjugates, which are involved in many important biological processes. Analyzing the interactions of glycans with proteins, lipids, and other biomolecules is crucial for understanding cellular processes, discovering therapeutic targets, developing therapeutic drugs, etc. CD BioGlyco provides worry-free Glycoinformatics-assisted Glycan-molecular Interaction Analysis Services to help clients unlock the interaction information of glycans with molecules such as Proteins, Lectins, Lipids, etc. Glycan Molecular Mechanics (MM) Simulation is an advanced computational technique that combines classical MM with quantum mechanics (QM) to study the dynamic behavior and properties of glycans at the atomic level. This hybrid approach models glycan structure, energetics, and interactions in detail, capturing large-scale conformational dynamics and complex electronic properties of specific regions of glycan molecules.
We provide specialized glycan conformational dynamics prediction services to help clients use computational techniques and algorithms to model and predict the dynamic behavior and conformational changes of glycans. Our services are as follows:
Use advanced computational tools to create detailed 3D models of glycan structures to understand their structure and function.
Use molecular dynamics (MD) to simulate the conformational space of glycans and observe the movement and interaction of glycans at the atomic level under factors such as temperature, solvation effects, and pH over a specific period.
Analyze the data obtained from MD simulations to determine possible conformational states and transitions, identify major structures and transition states, and obtain information about the flexibility, stability, and reactivity of glycan structures.
Use nuclear magnetic resonance (NMR) and X-ray crystallography to verify the predicted conformations.

Results: The authors outline three methods for quantitative and qualitative assessment of the assembly process of glycoprotein or glycosphingolipid complexes: biacore analysis, molecular docking, and MD simulations. Biacore is used to measure small compounds or protein-protein complexes and does not require the use of fluorescent or radioisotope labels. Molecular docking is a computer simulation that studies the interactions between two or more component molecules. It calculates the conformers of glycans and proteins separately, and then assembles and scores the complex structure. MD uses the 3D structure of the complex to model and analyze the molecular interactions within the complex, revealing various glycan conformations with different energy levels.
