✦ Synopsis

Two standardized assays for determining the amount of native collagen in a collagen solution are described which are based on polarimetric measurements. Native collagen content is calculated from the loss of optical rotation during transition from the original to the denatured conformation using constants which were obtained from standard collagen of highest available native collagen content. While Method I gives information on the content of helical collagen, Method I1 estimates collagen which is resistant to peptic degradation. Both methods are simple to perform and suitable for routine quality control.

## Abstract An analysis of the available data on the enthalpy (Δ__H__~__r__~) of denaturation (melting) of collagens with different imino acid content in solution and in the aggregated state has shown that Δ__H__~__r__~ in solution increases with increasing denaturation temperature, whereas in the
