## Abstract By means of carbonβ13 nmr (at 25 MHz) the __trans/cis__ conformer ratio in glycylβLβproline has been measured in aqueous (D~2~O) solution over the temperature range 33β96Β°C. It is found that Ξ__H__^0^ = β4.2 kJ/mole and Ξ__S__^0^ = β9.7 J/mole/K. Measurements of the __T__~1~ values for
A series of novel copolymers of trans-4-hydroxy-L-proline (Hpr) and β£hydroxy acids [D,L-mandelic acid (DLMA) and D,L-lactic acid (DLLA)] were synthesized via direct melt copolymerization with stannous octoate as a catalyst. These new copolymers had pendant amine functional groups along the polymer b
