So far I've realized that if you combine figure "A" with itself it forms the desired product, but I'm not sure if there are any solutions. When you combine a with itself you form H2O (condensation) and NH
2CH
2CH
2CONHCH
2CH
2COOH. Now if that product continues to bind with A's it will continue as the chain described.
