Table 3.

depicts fecal levels of acetic acid, propionic acid, isobutyric acid, butyric acid, 2-methyl butyric acid, isovaleric acid, valeric acid, isocaproic acid, and caproic acid in RTT and WT rats at p35, p105, and p196. There were no significant differences in RTT and WT samples at any developmental timepoint measured. Values depicted are log2 transformed data values.
