Figure 6

Illustration of the wide range of relative percent abundances of Native and S-Cysteinylated albumin found in the human population. Data were acquired from human plasma obtained from A) an individual with congestive heart failure, diabetes, and a history of myocardial infarction (4.5% Native form), and B) a healthy individual (66% Native form). Deconvoluted "MH+" peaks are assigned as follows: 66254 = N-terminal truncation (-DA) (Calc. 66253), 66325 = N-terminal truncation (-D) (Calc. 66324), 66440 = Native/unmodified (Calc. 66439), 66538 = Non-covalent phosphate adduct (plasma anticoagulant artifact) (Calc. 66537), 66559 = S-Cysteinylated (Calc. 66558), 66602 = Glycated native form (Calc. 66601), 66721 = Glycated S-Cysteinylated form (Calc. 66720).
