✦ Synopsis

A series of poly(cg1utamic acid) esters have been synthesized and studied by optical rotatory dispersion, x-ray diffraction, and infrared spectrometry. The results obtained emphasize the importance of the outer portions of the side chains in determining both the stability and precise conformation of the a-helix.
