Edsall There were other implications of the ionic dipolar structure of the amino acids and peptides. The apparent molar volumes of alpha-amino acids in water proved to be some 13 cm3 smaller than those of isomeric polar but uncharged compounds; a comparison of glycine and glycolamide was the simplest example. The difference was due to the electrostriction of water molecules that were squeezed tightly around the charged groups by the electric field of the ion-dipole. The same mechanism also produced a marked lowering of the heat capacity of the system. These effects, of course, were already well known for ions. |
