WebThe three-dimensional structure of insulin is further stabilised by disulphide bridges. These form between thiol groups (-SH) on cysteine residues (CYS above). There are 6 cysteines, so 3 disulphide bridges are formed: 2 between the A and B chains (between A7 & B7, and A20 & B19), and one within the A chain (A6 & A11).

On the MCAT, close enough is good enough, and this is pretty darn close. This sounds like a great deal of work for an amino acid with just 2 side chains. But if you can understand the logic for a simple structure, you’ll be able to apply it to something more complex. http://labs.icb.ufmg.br/lbcd/pages2/agenor/p5/programas/Stryer/2.pdf how many eiffel towers are there
