Fig 2From: Dietary beet pulp decreases taurine status in dogs fed low protein dietVarious thiol concentrations in plasma (PL) and whole blood (WB) of the dogs fed the purified diets containing various fiber sources. a PL total cysteine (free + bound); b WB total glutathione (GSH + GSSG); c PL cysteinyl-glycine; d PL homocysteine. The values are expressed as mean ± SEM. The symbols represent the groups that have significant different (P < 0.05 unless otherwise mentioned in the text) at the time point (*significance between BP and RB and ***significance between RB and CL). From week 10, n = 5 for the BP group due to omission of one dog for excessive weight lossBack to article page
