structure of human insulin? that i can draw?

Answer 1

Cool, I never realised insulin looked so cool, this diagram looks pretty drawable: http://journals.iucr.org/d/issues/2003/08/00/en0087/en0087fig9.html
This one too (maybe): http://en.wikibooks.org/wiki/A-level_Chemistry/OCR_%28Salters%29/Engineering_Proteins

Aaaand this one is a super-cool one that you won't be able to draw because its 3D but you can move it around with your mouse.. http://www.vivo.colostate.edu/hbooks/pathphys/endocrine/pancreas/insulin_struct.html
