NAD+ — Research Guide

NAD+ (Nicotinamide Adenine Dinucleotide) is a fundamental coenzyme in cellular energy metabolism. Unlike most compounds in our catalog, NAD+ is a small molecule (not a peptide). It is one of the most-cited research substrates in mitochondrial-function, sirtuin-pathway, and cellular-bioenergetics literature.

Chemistry & identity

NAD+ (CAS 53-84-9, MW 663.43 g/mol) is a small-molecule coenzyme — a dinucleotide composed of nicotinamide and adenine linked through phosphate groups via two ribose sugars. Per-batch HPLC + MS verification.

Research applications

  • Sirtuin-pathway substrate-availability research
  • Mitochondrial respiratory-chain substrate studies
  • PARP-family enzyme substrate research
  • Cellular redox-state and NAD+/NADH ratio assays
  • Comparative studies with precursors (NMN, NR)

Stability & storage

Lyophilized NAD+ is stable at −20°C protected from moisture and light. Aqueous solutions are sensitive to pH extremes and oxidation; published research uses neutral-pH buffers and immediate refrigeration.

Published half-life range

12 min midpoint (lit. 0.1h – 0.5h)

Source: Cantó et al., Cell Metab 2012; tissue half-life longer than plasma. See the half-life calculator for predicted in-solution decay over time.

FAQ

NAD+ vs NMN — which is the research substrate?

NAD+ is the active coenzyme. NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) are biosynthetic precursors. Orion stocks NAD+ directly.

Why is the per-mg cost so low?

NAD+ is a small molecule, not a synthetic peptide. The synthesis cost and per-mg price scale very differently. At $17.99 for 100mg, the $/mg cost is one of the lowest in our catalog.

What's the in-solution stability?

Plasma half-life of free NAD+ is short (minutes); tissue half-life is longer. See published cell-biology literature and the half-life calculator.

Is this for human use?

No. In-vitro research use only.
