Model building for NMR experiments typically starts with the complete protein or nucleic acid chain, including [[Hydrogen in macromolecular models|hydrogen atoms]]. The distance restraints are then applied. The resulting model usually includes the entire protein and nucleic acid chains, unlike [[X-ray crystallography|X-ray crystallographic]] models that often lack the ends, and even loops in the middle of chains, due to [[Disorder|disorder]] in protein crystals. | Model building for NMR experiments typically starts with the complete protein or nucleic acid chain, including [[Hydrogen in macromolecular models|hydrogen atoms]].

Macromolecular structure determination by NMR is done at high protein concentrations in aqueous solution, and thus requires that the molecule be highly soluble.
