A selection of quick ‘go-to’ references for values such as scalar coupling constants in proteins, and chemical shifts


Scalar coupling constants:

Chemical Shifts:

BMRB database statistics (protein chemical shifts) here

Biomolecular structure:

PDB statistics


Misc:

Bionumbers - contains a great many random quantities such as cell volume, cellular concentration of ATP etc.
