| Description | Raffinose belongs to the class of organic compounds known as oligosaccharides. These are carbohydrates made up of 3 to 10 monosaccharide units linked to each other through glycosidic bonds. Raffinose is an extremely weak basic (essentially neutral) compound (based on its pKa). Within humans, raffinose participates in a number of enzymatic reactions. In particular, raffinose and D-galactose can be biosynthesized from stachyose; which is mediated by the enzyme Alpha-galactosidase a. In addition, raffinose can be converted into sucrose and D-galactose through the action of the enzyme Alpha-galactosidase a. The enzyme does not cleave β-linked galactose, as in lactose. In humans, raffinose is involved in galactose metabolism. Outside of the human body, Raffinose is found, on average, in the highest concentration within a few different foods, such as ginkgo nuts, soy beans, and mung beans and in a lower concentration in gram beans, dates, and coconuts. Raffinose has also been detected, but not quantified in, several different foods, such as summer savories, mexican groundcherries, summer grapes, american cranberries, and common hazelnuts. This could make raffinose a potential biomarker for the consumption of these foods. Either raffinose or sucrose is used as a base substance for sucralose. Raffinose is a trisaccharide composed of galactose, glucose, and fructose. These oligosaccharides pass undigested through the stomach and upper intestine. The raffinose family of oligosaccharides (RFOs) are alpha-galactosyl derivatives of sucrose, and the most common are the trisaccharide raffinose, the tetrasaccharide stachyose, and the pentasaccharide verbascose. In the lower intestine, they are fermented by gas-producing bacteria that do possess the α-GAL enzyme and make short-chain fatty acids (SCFA)(acetic, propionic, butyric acids) commonly associated with eating beans and other vegetables. 2-[(6-{[3,4-dihydroxy-2,5-bis(hydroxymethyl)oxolan-2-yl]oxy}-3,4,5-trihydroxyoxan-2-yl)methoxy]-6-(hydroxymethyl)oxane-3,4,5-triol is found in Arabidopsis thaliana, Origanum vulgare, Rehmannia glutinosa and Salacia oblonga. Raffinose can be hydrolyzed to D-galactose and sucrose by the enzyme α-galactosidase (α-GAL), an enzyme not found in the human digestive tract. |
