Why Analyze Nicotinate and Nicotinamide?
Nicotinate and nicotinamide are central building blocks for the nicotinamide adenine dinucleotide pool. Through de novo synthesis from tryptophan and salvage pathways that recycle nicotinamide and nicotinamide riboside, cells maintain NAD and NADP levels to support glycolysis, the TCA cycle, oxidative phosphorylation, fatty acid oxidation, and many other redox-dependent reactions.
When precursor levels are perturbed, you may see:
- Imbalanced NAD⁺/NADH or NADP⁺/NADPH ratios.
- Compensatory changes in de novo versus salvage pathways.
- Accumulation of downstream catabolites such as trigonelline or nicotinurate.
By profiling nicotinate, nicotinamide, and their derivatives alongside broader metabolomics data, you can:
- Clarify whether changes in NAD metabolism are driven by precursor limitation, pathway bottlenecks, or increased consumption.
- Link redox changes to nutrient status, cofactor metabolism, and one-carbon pathways.
- Support mechanism-of-action studies for compounds that modulate NAD biosynthesis or salvage.
What Our Nicotinate and Nicotinamide Analysis Service Includes
Our nicotinate and nicotinamide analysis is built as a targeted metabolomics panel that can stand alone or be integrated into wider cofactor and vitamin profiling.
Typical service modules include:
- Absolute quantification of nicotinate and nicotinamide in biofluids, tissues, cells, and other research samples.
- Extended panel of related metabolites, including key intermediates and catabolites for pathway interpretation.
- Custom panel design to add or remove analytes that are relevant to your model or intervention.
- Optional integration with NAD species (NAD⁺, NADH, NADP⁺, NADPH) and one-carbon metabolites via linked services.
- Data analysis and visualization, including group comparisons, ratios (for example nicotinate/nicotinamide), and basic pathway mapping.

Advantages of Our Nicotinate and Nicotinamide Analysis Service
- Sensitive LC–MS/MS quantification: Targeted methods capture low-abundance nicotinate/nicotinamide in small-volume samples.
- High calibration linearity: Calibration curves are tuned for strong linearity, typically with R² ≥ 0.99 across working ranges.
- QC-anchored reproducibility: Isotope-labeled internal standards and pooled QCs help keep batch-to-batch drift under tight control.
- Easy extension to cofactor networks: The same platform can be expanded to include NAD species, vitamins, one-carbon or CoA-related metabolites when you need broader pathway coverage.
Analytical Platform for Nicotinate and Nicotinamide Analysis
Core Instruments
Our nicotinate and nicotinamide panel is run on targeted LC–MS/MS platforms commonly used in small-molecule metabolomics.
UHPLC systems: High-performance UHPLC with binary pumps and autosamplers for low-volume injections and stable gradients.
Triple quadrupole mass spectrometers (primary quantification)
Representative platforms used in targeted metabolomics, such as:
- Thermo Scientific TSQ series triple quadrupole systems.
- AB Sciex QTRAP or API series triple quadrupole instruments.
These are operated in electrospray ionization (ESI), typically in positive mode, using MRM for nicotinate, nicotinamide, and related metabolites.
High-resolution MS (method development and confirmation, when needed)
Orbitrap or TOF-based instruments (for example Thermo Q Exactive or similar HRMS systems) can be used to confirm identities and refine transitions before locking the routine LC–MS/MS method.
