NAD+ is oxidised nicotinamide adenine dinucleotide, a nucleotide coenzyme. The supplied certificate names beta-NAD+ and reports NADH separately. Reading those entries starts with the chemical form each name represents.
NAD+ names and the represented molecular form
ChEBI CHEBI:15846 names the oxidised form and records CAS 53-84-9. Its displayed structure has net charge +1. The formula and average mass below belong to that particular representation; a different protonation state or added counterion needs its own specification.ChEBI: NAD+, CHEBI:15846 (opens in a new tab)

The supplied report specifies oxidised beta-nicotinamide adenine dinucleotide and comparison against a beta-NAD+ reference. It does not specify a complete salt or hydration formula, so the database representation should remain labelled as a reference rather than a full batch formula.NAD+ 1000 mg report: MA-NAD-0005 (opens in a new tab)ChEBI: NAD+, CHEBI:15846 (opens in a new tab)
NAD+ and NADH are different redox forms
ChEBI records NADH as the reduced form. Its separate NAD(1−) and NADH(2−) records show why net charge and redox identity must be read independently: a minus sign in the charge field does not by itself identify NADH.ChEBI: NADH, CHEBI:16908 (opens in a new tab)ChEBI: NAD(1−), CHEBI:57540 (opens in a new tab)ChEBI: NADH(2−), CHEBI:57945 (opens in a new tab)
An explicitly hypothetical mixture of 90 units NAD+ and 10 units NADH totals 100 units and has an NAD+/NADH ratio of 9. A 50:50 mixture has the same total but a ratio of 1. This arithmetic illustrates why both measured forms are needed for the ratio.ChEBI: NAD+, CHEBI:15846 (opens in a new tab)ChEBI: NADH, CHEBI:16908 (opens in a new tab)
Read the coenzyme-specific certificate
Report MA-NAD-0005, revision 01, identifies lot NAD-05-9NW. It reports beta-NAD+ chromatographic assay of 99.38%, NADH of 0.14%, ADP-ribose of 0.18% and measured NAD+ content of 1002.00 mg. These are distinct report fields, not interchangeable ways of expressing the same quantity.NAD+ 1000 mg report: MA-NAD-0005 (opens in a new tab)
Preserve the analyte names, analytical methods and units when transcribing the report. A percentage based on chromatographic area should remain labelled that way; the milligram content belongs in its own entry.NAD+ 1000 mg report: MA-NAD-0005 (opens in a new tab)
