## Abstract The 218‐nm peak, characteristic of the circular dichroism of randomly coiled poly‐α‐amino acids can be demonstrated in solutions of penta‐L‐lysine, α‐glycyl‐L‐lysine, as well as poly‐L‐lysine. The thermal stability of the particular state that gives rise to this 218‐nm band in the CD is
