## Abstract Enthalpy changes [as determined by differential scanning calorimetry (DSC)] and optical rotation changes over the helix โ coil transition were measured for various gelatin solutions and films. From these studies it has been concluded that: (1) a linear correlation between ฮ__H__ and ฮ[ฮฑ
