Term Definition
Butyric acid
A carboxylic acid with the formula CH3(CH2)2COOH made by microorganisms. This oily, colourless liquid is responsible for part of the noxious odour from rancid butter or vomit. Epigenetic relevance: butyric acid enhances the transcriptional activity at promoters which are typically silenced/downregulated due to histone deacetylase activity.
