Medium-chain aldehydes are an aldehyde with a chain length containing between 6 and 12 carbon atoms. Thus, 5-decenal is considered to be a fatty aldehyde lipid molecule. 5-decenal is practically insoluble (in water) and an extremely weak acidic compound (based on its pKa). 5-decenal can be found in coriander, which makes 5-decenal a potential biomarker for the consumption of this food product.
