Summary of the Tissue Metabolite Concentrations (µmol/g wet wt) Measured Enzymatically from Extracts of C6 Wild Type and Clone D27 Tumors.

Tumor	N	Glucose	Lactate	ATP	Phosphate
C6	5	2.54 ± 0.2	7.38 ± 0.8	0.77 ± 0.1	6.59 ± 0.8
D27	5	1.41 ± 0.2*	7.44 ± 0.4	0.75 ± 0.1	5.56 ± 1.1

N is the number of tumors studied. Results are mean ± 1 SEM. Significantly lower concentrations of glucose were measured in the D27 tumors.
