AICAR

AICAR – Research-Grade Aminoimidazole Carboxamide Riboside

AICAR (5-Aminoimidazole-4-carboxamide riboside) is a synthetic nucleoside analog structurally related to endogenous intermediates involved in cellular energy regulation pathways. Unlike peptide-based research compounds, AICAR is a small-molecule riboside that participates in biochemical processes through intracellular metabolic conversion. In laboratory research settings, AICAR is utilized as a reference material for studying energy-sensing mechanisms, nucleotide metabolism models, and signaling pathways associated with cellular metabolic regulation.

Due to its low molecular weight and non-peptide structure, AICAR exhibits physicochemical properties that differ from regulatory peptides and protein hormones. This distinction allows researchers to investigate small-molecule transport, intracellular conversion pathways, and enzyme-mediated signaling behavior in vitro. Its defined chemical structure and reproducible synthesis support controlled use in mechanistic assays, metabolic pathway studies, and exploratory biochemical research conducted under controlled laboratory conditions.
