What is ATP/AMP/NALT Based Amino Blend?

ATP/AMP/NALT Based Amino Blend is a seven-component research solution that combines three adenine nucleotides and cofactors (NAD⁺, ATP and AMP) with a methyl donor (betaine), a phosphatidylcholine-pathway intermediate (CDP-choline), an acetylated aromatic amino acid (NALT) and L-arginine hydrochloride. Despite the name, it is not a peptide and not an ATP-only product: L-arginine hydrochloride is the largest component at 175 mg/mL, and the nucleotides total 65 mg/mL.

The components map to three pieces of cell chemistry:

• Adenylate energy sensing, where AMP-activated protein kinase reads the ATP-to-AMP ratio (Hardie et al., 2012)
• NAD⁺ redox (Krebs Cycle) and Salvage Pathway (Covarrubias et al., 2021)
• One-carbon and phospholipid metabolism through Betaine (TMG) and CDP-choline (Obeid, 2013; Gibellini & Smith, 2010).

What the blend does at the bench is supply these defined substrates together, in fixed per-mL amounts, for assay panels that need them in one solution.  Batch-verified at Modern Aminos, it is supplied in one laboratory format, a 20 mL Amber vial. The carrier is a water-based solution with benzyl alcohol (1%) as the preservative. Per-mL composition:

• NAD+: 20 mg/mL
• Betaine Anhydrous (TMG): 30 mg/mL
• CitiCholine (CDP-Choline): 45 mg/mL
• N-Acetyl L-Tyrosine (NALT): 35 mg/mL
• L-Arginine HCl: 175 mg/mL
• ATP (Adenosine Triphosphate, Disodium): 40 mg/mL
• AMP (Adenosine Monophosphate): 5 mg/mL

Laboratories building metabolic panels often place it next to public reference listings such as DADA (Diisopropylamine Dichloroacetate), ITPP (Myo-inositol trispyrophosphate).

Chemical and Molecular Data for ATP/AMP/NALT Based Amino Blend

What are the Mechanisms of Action?

The pathway chemistry behind ATP/AMP/NALT Based Amino Blend in laboratory research includes:

• Adenylate energy charge: AMP-activated protein kinase senses falling ATP relative to AMP and ADP through nucleotide binding at its γ subunit (Hardie et al., 2012); this blend supplies ATP and AMP together at 40mg and 5 mg per mL.
• NAD⁺ redox and signaling: NAD⁺ is the hydride acceptor of dehydrogenase reactions and a consumed substrate of sirtuins, PARPs and CD38; nicotinamide released by those enzymes is recycled to NAD⁺ through NAMPT and NMNAT in the salvage pathway (Covarrubias et al., 2021).
• Kennedy pathway intermediate: CDP-choline (citicoline) is the activated intermediate of de novo phosphatidylcholine synthesis: choline kinase forms phosphocholine, CTP:phosphocholine cytidylyltransferase forms CDP-choline, and cholinephosphotransferase transfers phosphocholine to diacylglycerol (Gibellini & Smith, 2010).
• Methyl donor: Betaine (trimethylglycine) donates a methyl group to homocysteine through betaine-homocysteine methyltransferase, forming methionine and dimethylglycine (Obeid, 2013); betaine itself is formed by oxidation of choline (Zeisel, 2013).
• Acetylated tyrosine: NALT is L-tyrosine carrying an acetyl group on the α-amino nitrogen (ChEBI:21563); free L-tyrosine is the substrate of tyrosine hydroxylase, the rate-limiting enzyme of catecholamine synthesis (Daubner et al., 2011).
• Arginine branch point: L-arginine is the substrate of the nitric oxide synthases, which oxidize its guanidino nitrogen to nitric oxide and L-citrulline using NADPH, O₂ and tetrahydrobiopterin (Förstermann & Sessa, 2012). Arginase competes for the same pool, hydrolyzing L-arginine to L-ornithine and urea (Wu & Morris, 1998).
