Abstract

<p>Oligomerization of alanine was observed by pressurizing its solid-free aqueous solution. Co-occurring solidifications of alanine and H<sub>2</sub>O as immiscible phases at high pressure were found to be crucial for concentrating the solute, alanine. The pressure-induced freeze concentration also enhances the pressure-induced oligomerization.</p>
