Figure 1From: In vitro study of uptake and synthesis of creatine and its precursors by cerebellar granule cells and astrocytes suggests some hypotheses on the physiopathology of the inherited disorders of creatine metabolismAnalysis by MS/MS: fragmentation by collision-induced dissociation (CID). Fragmentation pattern and selected ion transitions (m/z) of butylated [1,2-13 C2,15N3]GAA and [1,2-13 C2,15N3]Cr used for MS/MS analyses are shown.Back to article page
