NMR Relaxation and Diffusion Data for Aggrecan Solutions

Featuring proton nuclear magnetic resonance measurements of water in aggrecan solutions. It includes longitudinal and transverse relaxation rates at 9.4 T and 0.5 T field strengths, diffusion coefficients, and derived activation energies across a range of temperatures and aggrecan concentrations from 0 to 5.3% w/w.

Use Cases

• Model the concentration dependence of transverse relaxation rates at high field to study chemical exchange effects.
• Analyze the relationship between aggrecan concentration and water diffusion coefficients measured via pulsed field gradient NMR.
• Calculate activation energies for relaxation processes and translational motion using temperature dependencies.
• Compare longitudinal relaxation rates and inverse diffusion coefficients across the 0–5.3% w/w aggrecan concentration range.

Strengths

• Data includes measurements at two distinct magnetic field strengths (9.4 T and 0.5 T).
• Covers a defined aggrecan concentration range of 0–5.3% w/w.
• Derived activation energies are provided for relaxation and diffusion processes.

Limitations

• Sample size and number of data points are not specified.
• Data is specific to aggrecan in aqueous salt solutions, limiting generalizability to other macromolecules.
• The dataset is static with no update frequency, last updated in June 2020.
