Abstract
Butyrate is one of the three principal short chain fatty acids (SCFA) in humans generated by colonic microbial fermentation of dietary substrates. SCFA are the C2-5 organic fatty acids, also called the volatile fatty acids (VFA), which include acetate, propionate and butyrate. Colonic intraluminal levels of butyrate may play a role in the pathogenesis of a variety of diseases of the large intestine. This chapter reviews the production, absorption, metabolism, and therapeutic implications of butyrate.
