NAD+

Product Overview

NAD⁺ (Nicotinamide Adenine Dinucleotide, oxidized form) is a naturally occurring dinucleotide composed of two nucleotides joined through a pyrophosphate linkage. The molecule consists of an adenine nucleotide and a nicotinamide nucleotide linked via their phosphate groups. The compound features a β-glycosidic bond connecting the nicotinamide to the ribose sugar.

Technical Specifications

Structural Context

NAD⁺ is a dinucleotide consisting of two nucleoside monophosphates joined by a pyrophosphate bridge. The molecule contains an adenine moiety linked to ribose-5-phosphate, and a nicotinamide moiety linked to ribose-5-phosphate. The nicotinamide ring is an oxidized pyridine derivative, characterized by its ability to accept electrons in controlled redox reactions. The presence of multiple phosphate groups provides a highly polar, water-soluble molecular architecture. The distinctive UV absorbance profile (λmax ~260 nm) makes this compound suitable for analytical method development, chromatographic reference studies, spectrophotometric quantification, and stability profiling under varying buffer conditions in controlled laboratory environments.

Handling and Storage

The product is supplied in lyophilized (freeze-dried) powder form. For optimal stability, store lyophilized material at or below -20°C. Protect from repeated freeze-thaw cycles, moisture, and prolonged exposure to light, heat, and alkaline conditions.
