Metabolite profile comparisons between ascending and descending colon tissue in healthy adults

Figure 4 Composition of microbiota from stool, ascending and descending colon in a healthy, normal weight adult. Left side shows principal components analysis biplots of centred log-ratio transformed relative abundances at the phylum; A: Family; B: Genus; C: Levels. Lines with arrows represent individual taxa. Right side shows relative abundance bar charts for the most abundant taxa at the respective taxonomic level across stool and colon location sample types.
