Key Points

The study aims to investigate how dehydration affects the dynamics of native collagen proteins using solid-state NMR spectroscopy.
Utilized solid-state NMR spectroscopy to examine native collagen samples under varying dehydration conditions.
Analyzed C relaxation to assess the water-mediated dynamics of collagen.
Evaluated motional heterogeneity in the collagen structure.
Dehydration significantly altered the C relaxation dynamics in collagen (p < 0.01).
Identified increased motional heterogeneity in dehydrated states compared to hydrated states, suggesting changes in protein stability.
Established correlation between water content and relaxation rates in native collagen.
