摘要: 1. 1. Samples of collagen (tendon, skin, cuticle) swell in acid solution. A study has been made the effect temperature upon this swelling at pH I for a wide range collagens. 2. 2. Below characteristic (TT), given collagen, is reversible. 3. 3. At, or above TT second irreversible takes place. 4. 4. found to agree well with TD (the melting point tropocollagen molecule dilute solution) collagen. The one exception Ascaris cuticle. 5. 5. Both and give linear correlation total pyrrolidine content. 6. 6. method constitutes simple preliminary way determining without necessity extracting soluble
