Introduction The 2D chemical structure image of PENTYL BUTYRATE is also called skeletal formula, which is the standard notation for organic molecules. This ester has a smell reminiscent of pear or apricot. Because the short-chain fatty acids (SCFAs) produced by bacterial fermentation of carbohydrates in the human gut are so essential to many of the microbiota-mediated effects on human metabolism, we decided to investigate how SCFAs specifically, butyrate are synthesized by our microbial companions.
