From: 13C tracer analysis suggests extensive recycling of endogenous CO2 in vivo
Plasma citrate M + 1 appears earlier than M + 3. Time course of citrate M + 1 and M + 3 in the liver (A), skeletal muscle (B), and plasma (C) of mice receiving [U-13C]-glucose infusion for 3 h (h). For data in A and B, n = 1. Data in C are presented as mean ± SD n = 5 animals per group for the plasma sample only. Data in this figure was after natural abundance correction
