Short chain fatty acids (SCFA) are volatile fatty acids produced by the gut microbiota in the large bowel as fermentation products from food components that are unabsorbed/undigested in the small intestine; they are characterized by containing fewer than six carbons, existing in straight, and branched-chain conformation. (Ríos-Covián D, Ruas-Madiedo P, Margolles A, Gueimonde M, de Los Reyes-Gavilán CG, Salazar N. Intestinal Short Chain Fatty Acids and their Link with Diet and Human Health. Front Microbiol. 2016 Feb 17;7:185. doi: 10.3389/fmicb.2016.00185. PMID: 26925050; PMCID: PMC4756104.)
Note
Most volatile fatty acids are also short chain fatty acids, but not all short chain fatty acids are volatile enough to be considered volatile fatty acids. In some cases they are used interchangeably.
