Short-chain fatty acids (SCFAs) are bacterial metabolites produced by components of the microbiome. Gas chromatography (GC) is the most common method to analyze fatty acids (FAs). CD BioGlyco is the leader in the field of Fatty Acid Analysis. Our scientists have been committed to the research of FAs analysis and accumulated rich experience. We provide customers with analysis services of a variety of SCFAs by GC.
SCFAs are organic fatty acids with 1-6 carbon atoms. The main production site of SCFAs is in the colon, which is mostly produced by anaerobic fermentation of carbohydrates in undigested and absorbed food residues, mainly including acetic acid, propionic acid, and butyric acid. SCFAs participate in different metabolisms and perform different functions in the human body. Among them, acetic acid is an important source of energy for host cells; Propionic acid enters the liver through blood circulation, is catabolized in the liver, and participates in the process of reverse conversion of pyruvate to glucose; Butyric acid is the main energy source for epithelial cells.
SCFAs exhibit important physiological functions, which reduce intestinal inflammation, improve intestinal epithelial barrier function, and inhibit colon tumors, non-alcoholic fatty liver disease, obesity, and other diseases. In short, it plays an irreplaceable role in maintaining body homeostasis and normal physiological metabolism. Therefore, appropriate analytical techniques are essential for the sensitive and accurate quantification of SCFAs.

SCFAs are produced by fermentation of resistant starch and dietary fiber from the gut microbiota. The most important SCFAs are acetic acid (C2), propionic acid (C3), and butyric acid (C4). CD BioGlyco provides acetic acid, propionic acid, isobutyric acid, butyric acid, 2-methylbutyric acid, isovaleric acid, valeric acid, 2-methylvaleric acid, caproic acid, isocaproic acid, 3-methylvaleric acid, and 3-hydroxyiso valeric acid analysis services. We use GC to quantify SCFAs. Quantify SCFAs in the serum, colonic luminal content, and feces of mice by GC: 1) Sample preparation; 2) Sample analysis; 3) Data analysis.
