Insulin has 3 disulphide bridges
The number of disulphide bridges in the whole of insulin molecule is three because there are two bridges between alpha n beta chain and in alpha chain there is an intra disulphide bridge between aa 6 and aa 11. Intet disulphide bridges occur between 10th aa of both chains and at 20th aa of alphachain with 19th aa of beta chain.
