Our studies on the solution conformation of (Gly-Pro-Sar), and (Gly-Sar-Pro), synthesized as polypeptide models for collagen are reported. It is found that, while (Gly-Pro-Sar), exists in ordered triple-helical conformation, (Gly-Sar-Pro), remains as a disordered random coil in water. Addition of ce

Measurements of the molecular weight of (Pro-Pro-Gly), and (Pro-Pro-Gly),(Ala-Pro-Gly),(Pro-Pro-Gly),, which were synthesized by the solid-phase method, revealed that they formed a trimer in an aqueous solution, and dissociated into single-stranded chains on warming. Accompanying the transition, a l

We have synthesized (Pro-Pro-BAla), as a model for collagen. The synthetic polytripeptide, mol wt 6.500, exhibits a large negative optical rotation with a very strong negative Cotton effect centered a t 216 nm. The optical rotatory dispersion of (Pro-Pro-BAla), followed a single-term Drude equation
