Data presented for [6, 6- 2H2] glucose rate of appearance (Ra total) and disappearance (Rd) and Rd expressed as % of Ra. Contribution of exogenous [U-13C] glucose from the gut (Ra Gut) and endogenous glucose production (EGP) to Ra total are presented. Groups as per Table 1.
*indicates significantly lower than EX and EX+PRO (P<0.05). Values are presented as means ± SEM over 120 min OGTT.
