A large number of oligosaccharides have been prepared by partially breaking down more complex carbohydrates (polysaccharides). Most of the few naturally occurring oligosaccharides are found in plants. Raffinose, a trisaccharide found in many plants, consists of melibiose (galactose and glucose) and fructose.Click to see full answer. Furthermore, is raffinose a monosaccharide?Oligosaccharides are carbohydrates made up of a small number of monosaccharide units and are relatively smaller than polysaccharides. An example of an oligosaccharide is raffinose. Raffinose is a trisaccharide, meaning it is made up of three monomers of monosaccharides, namely galactose, glucose, and fructose.Subsequently, question is, is raffinose a Ketose? Raffinose is a trisaccharide composed of galactose, glucose, and fructose. 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. α-GAL also hydrolyzes other α-galactosides such as stachyose, verbascose, and galactinol, if present. In this regard, what kind of saccharide is raffinose? The raffinose family of oligosaccharides are α-galactosyl derivatives of sucrose. The most common are the trisaccharide raffinose (composed of galactose, fructose, and glucose) and the tetrasaccharide stachyose. These oligosaccharides are found in sugar beet molasses and whole grains.What is oligosaccharides and polysaccharides?Monosaccharides combine to make up more complex carbs. Oligosaccharides are typically made up of less than 20 monosaccharides, whereas polysaccharides can be made of even more. They’re in a gray area, because they’re not as complex as most polysaccharides — but they’re more complex than monosaccharides.
