ACOXL (Acyl-CoA Oxidase-Like) is a protein related to the acyl-CoA oxidase family, which plays a key role in the β-oxidation of very long-chain fatty acids within peroxisomes. Although its precise metabolic function is not yet fully understood, ACOXL is believed to contribute to lipid metabolism and the regulation of fatty acid breakdown. Research into ACOXL may offer insights into metabolic disorders and diseases associated with lipid storage and oxidation.
