Frequently Asked Questions

: What exactly is NAD+ peptide for sale at Apeptide?
A: NAD+ (Nicotinamide Adenine Dinucleotide) is an essential coenzyme found in every living cell. It functions as an electron carrier in redox reactions and serves as a substrate for sirtuins, PARPs, and CD38. It is supplied strictly for laboratory investigation and research purposes, not for human consumption. NAD+ peptide for sale

: What purity levels do you guarantee for NAD+?
A: We guarantee ≥99% purity, verified by HPLC testing with Certificates of Analysis available for every batch. Each COA provides detailed purity analysis, mass spectrometry confirmation (663.43 g/mol expected), and batch-specific data.

: What is the CAS number for NAD+?
A: The CAS number for NAD+ (oxidized form) is 53-84-9 .

: What is the molecular weight of NAD+?
A: The molecular weight is 663.43 g/mol .

: What is the difference between NAD+ and NADH?
A: NAD+ is the oxidized form that accepts electrons; NADH is the reduced form that donates electrons. The NAD+/NADH ratio is a critical indicator of cellular redox status and mitochondrial health .

: Why do NAD+ levels decline with age?
A: NAD+ levels decline with age due to increased consumption by CD38 and PARPs, reduced synthesis via NAMPT, and overall metabolic dysregulation .

: What are sirtuins and why are they important?
A: Sirtuins (SIRT1-7) are NAD+-dependent deacetylases that regulate aging, metabolism, stress resistance, and inflammation. They require NAD+ as a cofactor .

: Is your NAD+ for human consumption?
A: Absolutely not. Our NAD+ is strictly for research and laboratory use only. It is not for human consumption, clinical application, or any use involving humans or animals. All products are labeled “FOR RESEARCH USE ONLY.”

: How should I store NAD+ upon receipt?
A: NAD+ should be stored at -20°C (freezer) immediately upon receipt, protected from light and moisture. It is highly hygroscopic and should be kept desiccated. Avoid repeated freeze-thaw cycles.

: What solvent should I use for reconstitution?
A: For most research applications, sterile water, PBS (pH 7.4), or cell culture medium is appropriate. NAD+ is soluble in aqueous buffers. Contact our technical team for application-specific recommendations.

The Science Behind NAD+: The Central Molecule in Aging and Metabolism

NAD+ was discovered in 1906 by Sir Arthur Harden and William John Young, who identified it as a cofactor required for fermentation . The molecule’s structure was elucidated in the 1930s, revealing its role as an electron carrier in redox reactions .  NAD+ peptide for sale

In recent decades, NAD+ has emerged as a central regulator of aging and metabolism. Key discoveries include:

Sirtuins (1990s-2000s): The discovery that sirtuins are NAD+-dependent deacetylases linked NAD+ metabolism to aging and stress resistance . SIRT1 activation by NAD+ promotes mitochondrial biogenesis, stress resistance, and longevity.

PARPs and DNA Repair: PARP enzymes consume NAD+ to facilitate DNA repair, linking NAD+ availability to genomic stability . PARP activation during DNA damage depletes NAD+ levels, contributing to age-related NAD+ decline.  NAD+ peptide for sale

CD38 and Inflammation: CD38, an NAD+ glycohydrolase, is upregulated with age and inflammation, consuming NAD+ and contributing to age-related decline .

NAD+ Precursors: NMN (nicotinamide mononucleotide) and NR (nicotinamide riboside) have been identified as NAD+ precursors that can restore NAD+ levels in aging models .

The decline in NAD+ levels with age is now recognized as a hallmark of aging, contributing to mitochondrial dysfunction, metabolic dysregulation, and increased susceptibility to age-related diseases . NAD+ supplementation strategies have emerged as a major research focus in gerontology.
