Metabolic & NAD+ Research

This pathway spans more compound classes than any other in the catalogue: NAD+ itself, the mitochondrial-derived peptide MOTS-c, the mitochondria-targeting tetrapeptide SS-31, the enzyme inhibitor 5-Amino-1MQ, the growth hormone fragment AOD9604, and L-Carnitine. Not all are peptides — NAD+ is a dinucleotide coenzyme, 5-Amino-1MQ a small quinolinium molecule, L-Carnitine a quaternary ammonium compound — so materials are grouped here by area of study rather than by chemistry. Quantity per unit varies more widely than elsewhere, from 5 mg to 1000 mg.
