in similar experiments using reversed phase high-performance liquid chromatography to separate the phosphoamino acids , the 32p-labeled phosphoamino acid behaved like the 1-isomer of phosphohistidine , in not being retained by the column , and unlike 3-phosphohistidine , phosphoserine , phosphothreonine , phosphotyrosine , and phosphoarginine , which were all retained on the column .
