What is raffinose point out its significance?
Raffinose family of oligosaccharides (RFOs) are α-1, 6-galactosyl extensions of sucrose (Suc). This group of oligosaccharides is found in plants and is known to serve as desiccation protectant in seeds, as transport sugar in phloem sap and as storage sugars.
How many glycosidic linkages are in a Verbascose?

What do you mean by raffinose?
Definition of raffinose : a crystalline slightly sweet sugar C18H32O16 obtained commercially from cottonseed meal and present in many plant products.
What is verbascose made up of?
Verbascose, the pentasaccharide of the raffinose family of oligosaccharides, consists of galactose units joined to sucrose. In pea (Pisum sativum) seeds, the content of verbascose is highly variable.
What is stachyose made of?
Stachyose is a tetrasaccharide consisting of sucrose having an alpha-D-galactosyl-(1->6)-alpha-D-galactosyl moiety attached at the 6-position of the glucose. It has a role as a plant metabolite and a mouse metabolite.
How is raffinose broken down?
Dietetics: Raffinose can be hydrolyzed to sucrose and galactose by the enzyme α-galactosidase (α-GAL). Humans do not possess the α-GAL enzyme in their small intestine to break down the trisaccharide.
How is raffinose formed?
They are formed from sucrose with the ensuing addition of galactose moieties donated from galactinol. RFOs are abundant in plants and serve as desiccation protectant in seeds, as transport sugar in phloem sap and as storage sugars.
What is Verbascose made of?
Verbascose is a pentasaccharide that is stachiose which has an additional unit of alpha-D-galactopyranose attached by a 1->6 glycosidic linkage to the terminal galactosyl residue. It is a pentasaccharide and a raffinose family oligosaccharide. It derives from a stachyose.
Where is Verbascose found?
verbascose A non‐digestible tetrasaccharide, galactose‐galactose‐glucose‐fructose, found in legumes; fermented by intestinal bacteria and causes flatulence.
How is raffinose made?
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. It has a chemical formula of C 18H 32O 16. The galactose is connected to glucose by 1α→6 glycosidic linkage.
Is glucose a disaccharide?
A disaccharide (also called a double sugar or biose) is the sugar formed when two monosaccharides are joined by glycosidic linkage. Like monosaccharides, disaccharides are simple sugars soluble in water….Common disaccharides.
