Two of these chains consist of the purple A and lowercase alpha. Two of these chains consist of the blue B and the beta chain, the orange one and two of these are our gamma. So the green ones so we have these green, those are the gamma we have, these are the orange ones, those are the beta. We have these light blue ones, those are the BS. We have these purple uppercase A's and then we have these red lowercase alphas. And so we have many different chains found in a single fibringen molecule.
