HBHA(CO)NH

{
  "id": "MLC-T-CHM-013146",
  "term": "HBHA(CO)NH",
  "field": "Chemistry",
  "definition": "A three-dimensional nuclear magnetic resonance spectroscopy experiment used to correlate the chemical shifts of an amide proton and its attached nitrogen with the alpha and beta protons of the preceding amino acid residue. The magnetization transfer pathway proceeds from the alpha and beta protons (HA, HB) to the carbonyl carbon (CO) and then to the amide group (NH) of the next residue. This experiment provides sequential connectivity information for assigning protein backbone resonances.",
