Notes:
Sequenced polytripeptides, (Pro-Pro-Gly)n, (n = 10, 15, 20), with defined molecular weights were synthesized by the solid-phase method. Conformational changes of these sample as a function of temperature were studied by measurements of optical rotation and sedimentation equilibrium. The temperature dependence of optical rotation was shown similar to thermal transition of collagen molecule. Each of these polymers existed as a timer at lower temperature. (Pro-Pro-Gly)10 existed as a monomer at higher temperature, and the others were expected to behave analogously.
