These are published properties of the molecule, given for identification. Values we cannot confirm are omitted rather than estimated. What these terms mean.

What this compound is

Not a peptide at all: a redox cofactor built from nicotinamide and adenine, each on a ribose, joined by a diphosphate bridge. Every heavy atom is present - C21 N7 O14 P2 - with hydrogens omitted.

Molecular formula

C21H27N7O14P2

This compound is not a peptide, so it is identified by molecular formula rather than by an amino-acid sequence.
