Glycerol parameters in the three groups. The glycerol appearance after an overnight fast was higher in the TD group compared with the control group and TD + TP group. (A) The parameters of gluconeogenesis from glycerol such as glycerol converted to glucose (%), glucose derived from glycerol (%) and gluconeogenesis from glycerol was higher (p < 0.05) in the TD group than in the control and TD + TP groups (B, C, D). *, P < 0.05, compared with the control group. #, P < 0.05, compared with the TD + TP group.
