Metabolite Identification
Common Name4-methylpent-2-enoyl-CoA
Description4-methylpent-2-enoyl-CoA is a member of the acyl-CoA thioester class of compounds, characterized by its enoyl structure. This metabolite plays a role in the metabolic pathway of branched-chain fatty acid degradation, specifically in the conversion of (R)-2-hydroxy-4-methylpentanoyl-CoA to 4-methylpent-2-enoyl-CoA through a dehydration reaction, which is identified as the most chemically demanding step in this reductive pathway (PMID:18337824 ). Its structure features a methyl group at the 4-position and a double bond between the second and third carbon atoms, contributing to its unique reactivity and function. Additionally, studies involving spectroscopic analysis have shown that 4-methylpent-2-enoyl-CoA, alongside other acyl-CoA derivatives, exhibits distinct long-wavelength absorption bands, indicating its interaction with enzymatic systems (PMID:5145911 ). This highlights its relevance in biochemical pathways, particularly those associated with energy metabolism and fatty acid synthesis.
