Metabolite Identification
Common Namealpha-ribazole
Descriptionalpha-ribazole is a riboside, a chemical class of nucleosides that consists of a ribose sugar bonded to a nitrogenous base. Its chemical structure features a ribose moiety linked to a 5,6-dimethylbenzimidazole base, which is integral to its role in various biochemical pathways. Alpha-ribazole (α-R) is notably found in the nucleotide loop of coenzyme B12 (CoB12), playing a critical role in the structure and function of this essential cofactor involved in various enzymatic reactions, including methylation and isomerization processes. CoB12 is crucial for the metabolism of certain amino acids and fatty acids, as well as in the synthesis of nucleotides. The presence of α-R in CoB12 highlights its importance in the biochemical pathways that facilitate cellular metabolism and energy production. Understanding the structural and functional aspects of alpha-ribazole contributes to the broader knowledge of coenzyme B12 and its associated metabolic pathways (PMID:29783174 ).
