✦ Synopsis

Abstract

Specific volumes at 25° of aqueous solutions of poly(N‐methyl acrylamide) and poly‐(ethylene oxide) have been measured, and the data obtained is compared with corresponding data on low‐molecular‐weight compounds. The results support the notion, that the volume changes following the interaction between aliphatic groups and water are positive. They are discussed with particular reference to pressure effects on protein conformations.

The peptide toxin bombolitin III [B(III)], originally isolated from bumblebee venom, has been shown to undergo a concentration-dependent conformational change from a random structure to an alpha-helix induced by aggregation. The aggregation process and the consequent folding results from a delicate
