                                Propionate is a short-chain fatty acid produced by gut microbiota, and its unique three-carbon structure sets it apart from more common even-chain fats. This unique structure is the key to answering the question: is propionate an odd chain fatty acid? Yes, it is, and this fundamental difference has significant implications for its metabolic fate and overall health effects.
