Application:	• Medium-Chain Fatty Acids Rescue Motor Function and Neuromuscular Junction Degeneration in a Drosophila Model of Amyotrophic Lateral Sclerosis.: This research explores the therapeutic potential of medium-chain fatty acids, including 4-methyloctanoic acid, in rescuing motor function and preventing neuromuscular degeneration in a fruit fly model of ALS (Dunn et al., 2023 ). Identification of muttony-related compounds in cooked mutton tallows and their flavor intensities subjected to phenolic extract from thyme (Thymus vulgaris L.).: The study identifies 4-methyloctanoic acid among other compounds responsible for the characteristic flavor of cooked mutton, demonstrating its impact on food flavor profiles (Wu et al., 2023 ). Effects of Allium mongolicum Regel ethanol extract on three flavor-related rumen branched-chain fatty acids, rumen fermentation and rumen bacteria in lambs.: This paper investigates the effects of Allium mongolicum extract on rumen fermentation and bacteria in lambs, highlighting the role of 4-methyloctanoic acid in flavor formation (Zhao et al., 2022 ). Identification and Inhibition of the Key Off-Odorants in Duck Broth by Means of the Sensomics Approach and Binary Odor Mixture.: This research identifies 4-methyloctanoic acid as a key off-odorant in duck broth and explores methods to inhibit its formation to improve food quality (Pu et al., 2022 ).
Biochem/physiol Actions:	Odor at 1.0% PG
Biochem/physiol Actions:	Taste at 10 ppm
General description:	4-Methyloctanoic acid is a branched fatty acid commonly used in the flavor and fragrance industries. This compound gives sweaty and goaty flavors to the mutton meat and goat′s milk cheese, respectively.
Other Notes:	Natural occurrence: Cooked mutton and lamb.
