## Abstract Poly(__N__^δ^‐carbobenzoxy, __N__^δ^‐benzyl‐L‐ornithine) (PCBLO) was prepared by the standard NCA method. PCBLO was converted into poly(__N__^δ^‐benzyl‐L‐ornithine) (PBLO) through decarbobenzoxylation with hydrogen bromide. The monomer __N__^δ^‐benzyl‐L‐ornithine was synthesized by reac

## Abstract The conformational changes of poly‐__N__^ε^‐glutaryl‐L‐lysine (PGL) and poly‐__N__^ε^‐succinyl‐L‐lysine (PSL) in various salt solutions were studied by use of ORD and potentiometric titration measurements. The addition of alkali metal salts to the fully ionized PGL or PSL solution cause
## Abstract Poly(__N__^ε^‐stearyl‐L‐lysine) and poly(__N__^ε^‐pelargonyl‐L‐lysine) were synthesized both by polymerization of __N__^ε^‐pelargonyl and __N__^ε^‐stearyl‐L‐lysine NCA and by acylation of poly(L‐lysine) with pelargonyl and stearyl chloride. This second route has proven to be very useful
## Abstract Uncharged poly(__N__^ε^‐methyl‐L‐lysine) (PMLL) and its isomer, poly(__N__^δ^‐ethyl‐L‐ornithine) (PELO), in alkaline solution (pH ca. 12) undergo a helix‐to‐β transition upon mild heating at 50°C or higher in a manner similar to that of poly(L‐lysine) (PLL). The rate of conversion follo
## Abstract X‐ray diagrams from oriented films and fibers of poly‐__N__^γ^‐carbobenzoxy‐L‐α,γ‐diaminobutyric acid (PCLB) and of poly‐__N__^δ^‐carbobenzoxy‐L‐ornithine (PCLO) have been examined. The conformation in the solid state for both polymers is that of an α‐helix, 18/5 for PCLB and 11/3 for P
