What are Short Chain Fatty Acids?

There are basically three main types of SCFA. They are Acetates, Propionates, and Butyrates. Of the three types, the acetates and propionates are beneficial, but they tend to transfer through the walls of the intestine and get metabolized in muscle or liver. Only the Butyrates remain in the digestive system and act as a food/energy source for the beneficial microflora.
