Fractional ethanol precipitation modulates the structure and function of Coprinus comatus mycelial polysaccharides: alleviation of DSS-induced injury in Caco-2 cells via regulation of mitochondrial function

This study elucidates the regulatory effect of ethanol precipitation concentration on the physicochemical properties and functional activities of CC mycelial polysaccharides, and reveals the potential of CCPJ-80 to ameliorate ulcerative colitis by modulating oxidative stress and mitochondrial function pathways, providing a scientific basis for developing CCPJ as a functional food or therapeutic agent.
