The interaction between D-and L-enantiomers of polylysine and potassium pectate was studied by means of CD, microcalorimetry, and osmometry. Upon binding with pectate, only poly (L-lysine) undergoes a coil to ␣-helix transition, while poly(D-lysine) remains in the disordered state. This suggest that

## Abstract Acetyl‐(dehydro‐Phe) and acetyl‐bis(dehydro‐Phe) groups have been attached to the ε‐amino group of the lysine residues of the copolymer poly(Glu^92^Lys^8^) by reacting this last with acetyl‐(dehydro‐Phe)‐azlactone and acetyl‐bis(dehydro‐Phe)‐azlactone, respectively. In the latter case
