Table 1 Relative abundance of hGH molecular forms in circulation (adapted from Bidlingmaier et al⁶). The percentages are approximate.

Isoforms	Per cent
22 kDa monomer	48
20 kDa monomer	9
Modified hGH (dimers and oligomers)	30
Acidic hGH (desaminated and acylated forms)	7
Fragmented hGH (17, 12, 5, 30 kDa)	Variable
