## Abstract Several modification of the arrangements of α‐helical molecules were found in the solid films of poly (γ‐ethyl‐L‐glutamate), depending on the casting solvent and the temperature. The helical conformation is somewhat looser than the normal 18‐residue, 5‐turn α‐helix. Using x‐ray diffract
Poly( g-glutamic acid) (PGA) hydrogels have been prepared from microbial PGA produced by Bacillus subtilis F-02-1, water-soluble carbodiimide (WSC), and alkanediamines such as 1,3-propanediamine (1,3-PD), 1,4-butanediamine (1,4-BD), and 1,6-hexanediamine (1,6-HD) in aqueous medium. The carboxyl grou
