## Abstract Short chain fatty acids (SCFAs) are metabolic by products of anerobic bacteria fermentation. These fatty acids, despite being an important fuel for colonocytes, are also modulators of leukocyte function. The aim of this study was to evaluate the effects of SCFAs (acetate, propionate, an

โฆ Synopsis
Short-chain (C,-C,) fatty acids account for 80%-70%
of the anions in the colon. Acetate (C,) is nontoxic in contrast to C,,,,-C, fatty acids (propionate, butyrate, isobutyrate, valerate, and isovalerate). which induce coma in animals and may be important in the patho-gen& of hepatic coma in humans. A n in-vitro fecal incubation eystem was used to map out short-chain fatty acid production in the presence of lactuloee, amino acids, albumin, or blood. Albumin and blood increased production of all C,-C, fatty acids. In contrast, lactulose waa converted to acetate only and increased fecal acidity. The degradation of amino acids, albumin, and blood to short-chain fatty acids was

## Abstract Increased plasma levels of free fatty acids (FFA) occur in states of insulin resistance such as type 2 __diabetes mellitus__, obesity, and metabolic syndrome. These high levels of plasma FFA seem to play an important role for the development of insulin resistance but the mechanisms invo
