Abstract
Dielectric properties of collagen and gelatin are studied in order to get detailed information concerning the properties of the incompletely crystallized part, and as a result to get more complete information about the structure of collagen. Two kinds of dielectric absorption, α- and β-absorption, are observed in the temperature range between -70°C and 200°C and in the frequency range between 30cps and 106cps. The dipoles which contribute to the molecular motions for α- and β-absorption are situated on the polypeptide main chain of the “band part” appearing in the electronmicrograph of collagen fibril. The activation energies of the absorptions are 24∼48 Kcal/mole and 12∼19 Kcal/mole, respectively.Keywords
