"5 V") from the following list: ['MHz']. Ignore this when more complicated descriptions are required. Warning: The "PubChem" column at position 2 in the ["NMR_METABOLITE_DATA"]["Metabolites"] table, matches a standard column name, "pubchem_id". If this match was not in error, the column should be renamed to the standard name or a name that doesn't resemble the standard name.
