General description

Undecanoic acid is a volatile free fatty acid that is reported to occur as a flavor compound in milk fat, cheese and meat lipids.

Application

• Undecanoic Acid and L-Phenylalanine in Vermiculite: Detection, Characterization, and UV Degradation Studies for Biosignature Identification on Mars.: This research focuses on the detection and characterization of undecanoic acid and L-phenylalanine in vermiculite, with potential applications for biosignature identification on Mars. The study also examines UV degradation, which is crucial for astrobiological research (McIntosh et al., 2024).


• Drugs Form Ternary Complexes with Human Liver Fatty Acid Binding Protein 1 (FABP1) and FABP1 Binding Alters Drug Metabolism.: This paper explores how drugs interact with human liver fatty acid binding protein 1 (FABP1), including the involvement of undecanoic acid, to form ternary complexes that influence drug metabolism. These findings have significant implications for pharmacology and drug development (Yabut et al., 2024).


• Enhancing antifungal and biocompatible efficacy of undecanoic acid through incorporation with chitosan-based nanoemulsion.: This study demonstrates the enhanced antifungal and biocompatible properties of undecanoic acid when incorporated into a chitosan-based nanoemulsion, highlighting potential biomedical applications for this compound (Sathiyaseelan et al., 2024).


• In Vitro Evaluation of Essential Oils and Saturated Fatty Acids for Repellency against the Old-World Sand Fly, Phlebotomus papatasi (Scopoli) (Diptera: Psychodidae).: This research evaluates the repellency of essential oils and saturated fatty acids, including undecanoic acid, against the Old-World sand fly. The findings provide insights into developing natural repellents for vector control (Temeyer et al., 2024).
