plant-polysaccharides
Plant polysaccharides are complex carbohydrate polymers—such as cellulose, starch, and pectin—that form the structural backbone of cell walls and serve as primary energy storage molecules in plants. These compounds play critical roles in plant growth, development, and stress responses, making them central to research on biomass composition, cell wall architecture, and plant–environment interactions. Understanding their biosynthesis and structural diversity has broad implications for agriculture, food science, and the development of sustainable plant-derived materials.

A sugar compound extracted from Dendrobium orchid stems was found to reduce gut inflammation in mice by calming the immune system, boosting antioxidant defenses, and improving the balance of beneficial gut bacteria.
DOP-a significantly reduced levels of three key inflammatory proteins (TNF-α, IL-6, IL-1β) in blood and colon tissue of colitis mice
The orchid fiber activated the Nrf2/HO-1 antioxidant pathway while simultaneously blocking the TLR4/NF-κB inflammatory signaling pathway
16S rRNA gut microbiota profiling showed DOP-a partially reversed harmful bacterial imbalances caused by DSS, enriching beneficial microbial taxa
