Genetically engineered insulin

Build human insulin from its A and B chains, the way recombinant DNA technology produced it in 1983.

Open the simulation

What to notice

Insulin made in bacteria avoids the allergies some patients had to insulin from cattle and pigs.

Key relation

Insulin = A chain + B chain linked by disulphide (–S–S–) bridges

Try this

Step to the last stage and count the disulphide bridges between the chains.

What you can change

• Step: 1 to 4
