Testosterone 22-34 homeobox C10 Homo sapiens 269-273 22173925-6 2012 Finally, the dissociation pathway of the protonated molecule of testosterone to m/z 97 was revisited and an alternative pathway was suggested that considers the exclusion of C-10 along with the inclusion of C-5, which was experimentally demonstrated with stable isotope labeling. Testosterone 64-76 homeobox C10 Homo sapiens 174-178 18407565-6 2008 The C-7, C-8, C-10, C-15 and C-16 residues of Tes, Cor and Adr consistently give rise to singlets or doublets with splittings of less than 0.5 ppm, indicating similar local conformations. Testosterone 46-49 homeobox C10 Homo sapiens 14-18
