Tributyrin (Glyceryl tributyrate), a neutral short-chain fatty acid triglyceride, is a stable and rapidly absorbed prodrug of Butyric Acid. Tributyrin diffuses through biological membranes and is metabolized by intracellular lipases, releasing effective butyrate directly into the cell in vivo. Tributyrin has potent antiproliferative, proapoptotic and differentiation-inducing effects.
