A heat map of 73 intracellular metabolites of S. cerevisiae strain EJ4 grown on four different carbon sources, glucose, galactose, xylose, or cellobiose, until the exponential growth phase. The x-axis labels represent the four different carbon sources with two different sampling timepoints, 1, mid-exponential phase; 2, late-exponential phase. All experiments were performed in five replicates
