## Abstract Studies have been made of the precipitation of poly‐L‐glutamic acid from dilute aqueous solutions, over the pH range where the α‐helical conformation is maintained. The major purpose is to establish the molecular conformation in the precipitate and to outline the mechanism of the precip
## Abstract Infrared and X‐ray diffraction studies have established that in the β‐precipitation region of poly‐L‐glutamic acid the chains are in the β‐conformation. Therefore, a major molecular conformational change has taken place upon precipitation. It is shown that the size of the α‐helical aggr
