Complex Carbohydrate Magnetic Resonance Database (CCMRD)
Carbohydrates are crucial for various life activities in living organisms. The Complex Carbohydrates Magnetic Resonance Database (CCMRD), a solid-state NMR database for complex carbohydrates developed at Michigan State University. The Solid-state NMR spectroscopy reveals the molecular structure and dynamics of insoluble complex carbohydrates.
