Mice, housed at 30°C or 6°C for 10 days, were administered with [U‐
13C]glucose (2 g/kg, IP). 15 minutes after injection, liver and muscle were harvested for metabolic enrichment assay.
m+6 glucose enrichment in liver.
Metabolic 13C enrichments in liver are shown as m+3 glycolysis intermediates, m+2 TCA cycle intermediates. GAP, glyceraldehyde 3‐phosphate; DHAP, dihydroxyacetone phosphate.
After normalizing to the glucose enrichment in the liver of each mouse, the relative metabolic 13C enrichments were shown as m+3 glycolysis intermediates and m+2 TCA cycle intermediates.
m+6 glucose enrichment in muscle.
Metabolic 13C enrichments in muscle are shown as m+3 glycolysis intermediates, m+2 TCA cycle intermediates.
