Gut microbes provide energy to the microbiota by digesting food residues and releasing metabolites for the gut, affecting the host if they enter the host's circulatory system. Conversely, intestinal metabolites can influence the composition, gene expression, and gut microbiota-derived metabolites. Structural changes and metabolic changes in the gut microbial community, as well as metabolic changes in the host's blood or tissues. tend to cause a variety of diseases, The point study of microbiome and metabolome can help discover microorganisms and metabolites that play key roles in the physiological and disease development processes and reveal related mechanisms. https://metabolomics.creat...
