<unk>  is preferred over glycosylated<unk>  to reflect the correct (non-enzymatic) process. Early literature often used glycosylated as it was unclear which process was involved until further research was performed. The terms are still sometimes used interchangeably in English-language literature. The naming of<unk>  derives from<unk>  type A being separated on cation exchange chromatography. The first fraction to separate, probably considered to be pure<unk>  A, was designated HbA0, and the following fractions were designated<unk> ,<unk> , and<unk> , in their order of elution. Improved separation techniques have subsequently led to the isolation of more subfractions.
