Figure 2From: Studies of the intermediary metabolism in cultured cells of the insect Spodoptera frugiperda using 13C- or 15N-labelled tracersIsotopolog composition of 13C-labelled nucleosides from S. frugiperda cells grown with a 1:99 mixture of [U-13C6]glucose and unlabelled glucose added to SF-900 II medium. The filled dot represents a 13C1 isotopolog detected at an abundance well above the natural abundance contribution. Bold lines indicate isotopologs with adjacent 13C-labelled carbon atoms that were transferred from the same molecule of [U-13C6]glucose. The numbers give the molar enrichments of the indicated isotopologs.Back to article page
