General description

Heptanoic acid is a short-chain fatty acid mainly found in the flavor volatiles of cheese, green tea, fruits of Malpighia glabra L and flowers of oyster rhoeo.

Application


  • Identification of Short-Chain Fatty Acids for Predicting Preterm Birth in Cervicovaginal Fluid Using Mass Spectrometry.: This research identifies Heptanoic acid among other biomarkers in cervicovaginal fluid that could predict preterm birth, demonstrating its potential in prenatal diagnostics (Hur et al., 2024) (Hur et al., 2024).
