✦ Synopsis

The synthesis and some of the physical-chemical properties of tricopolymers of L-glutamic acid, blysine, and L-alanine are reported here. The molar ratios of the * Amino acid analyses of these polypeptides yielded values within approximately 3.5% of the mole ratios of NCA's incorporated into the polymerization mixture.

The helix-coil transition has been studied by high-resolution NMR for three watersoluble polypeptides. Such systems are better models for protein behavior than those in TFA-CDC13 solvent. An upfield shift of ~7 cps is observed for the a-CH peak of poly(bg1utamic acid) and poly-clysine as the helix c

## Abstract Two electrophoretic components have been detected on the ascending boundary in unbuffered solutions of polyglutamic acid and polylysine under certain experimental conditions. If the conditions are favorable to aggregation, another maximum, the third in order, is formed on this boundary.
