Decoding dietary pectin: from structural complexity and microbial CAZyme–PUL networks to cross-feeding and host-beneficial metabolites
Abstract The interaction of pectin, as one of the most complex dietary glycans, with gut microbiota represents a typical pattern for shaping the gut microenvironment and human homeostasis. Pectin has a heterogeneous structure, characterized by homogalacturonan (HG), rhamnogalacturonan I (RG-I), and rhamnogalacturonan I...
