Name the three short chain fatty acids.

• A. Acetate; Propionate; Butyrate
• B. Acetate; Propionate
• C. Propionate; Butyrate; Valerate
• D. Butyrate; Propionate; Caproate

Answer: (A)

Short-chain fatty acids are fatty acids with up to six carbon atoms produced by gut bacteria fermenting dietary fiber. The three most commonly cited end products are acetate, propionate, and butyrate, with 2, 3, and 4 carbon atoms respectively. These SCFAs play important roles in energy metabolism: butyrate serves as the main energy source for colonocytes, while acetate and propionate are utilized by peripheral tissues and the liver. There are other fatty acids like valerate and caproate, but they are not considered the primary trio. So the three short-chain fatty acids are acetate, propionate, and butyrate.
