Figure 4. Glucose, NEFA, and insulin in rats following a glucose challenge.

Figure 4

(A) Plasma glucose and (B) NEFA in PQQ+ and PQQ− fasted rats given 2 g glucose/kg of body weight by oral gavage. Blood was collected at 2, 5, 15, 30, 60 and 90 min intervals. Although glucose clearance appeared compromised in PQQ− rats following a glucose challenge, at each of the time points, there was no statististically significant difference compared to the PQQ+ group. Similarly, there was no difference in NEFA between groups following the glucose challenge, and no differences between PQQ+ and PQQ− rats in baseline plasma glucose (C) or insulin (D).
