Metabolite Identification
Common Name1-Methylnicotinamide
Description1-Methylnicotinamide, also known as 1-methylnicotinamide or 1-methylnicotinamide, belongs to the class of organic compounds known as nicotinamides. These are heterocyclic aromatic compounds containing a pyridine ring substituted at position 3 by a carboxamide group. 1-Methylnicotinamide is possibly soluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). 1-Methylnicotinamide exists in all living species, ranging from bacteria to humans. 1-Methylnicotinamide participates in a number of enzymatic reactions, within cattle. In particular, S-Adenosylhomocysteine and 1-methylnicotinamide can be biosynthesized from S-adenosylmethionine and niacinamide; which is catalyzed by the enzyme nicotinamide N-methyltransferase. In addition, 1-Methylnicotinamide can be converted into N1-methyl-2-pyridone-5-carboxamide through the action of the enzyme aldehyde oxidase. In cattle, 1-methylnicotinamide is involved in the metabolic pathway called the nicotinate and nicotinamide metabolism pathway.

Reactions
S-Adenosylmethionine + Niacinamide → S-Adenosylhomocysteine + 1-Methylnicotinamidedetails
General function:
Nucleotide transport and metabolism
Specific function:
Oxidase with broad substrate specificity, oxidizing aromatic azaheterocycles, such as N1-methylnicotinamide, N-methylphthalazinium and phthalazine, as well as aldehydes, such as benzaldehyde, retinal, pyridoxal, and vanillin. Plays a key role in the metabolism of xenobiotics and drugs containing aromatic azaheterocyclic substituents. Is probably involved in the regulation of reactive oxygen species homeostasis. May be a prominent source of superoxide generation via the one-electron reduction of molecular oxygen. Also may catalyze nitric oxide (NO) production via the reduction of nitrite to NO with NADH or aldehyde as electron donor. May play a role in adipogenesis.
