The raffinose family of oligosaccharides (RFOs) are α-galactosyl derivatives of sucrose, the most common being the trisaccharide raffinose, the tetrasaccharide stachyose, and the pentasaccharide verbascose.
The major raffinose compounds are raffinose (trisaccharide) and stachyose (tetrasaccharide), but higher oligomers can also be found in some plants. In Lamiaceae, Cucurbitaceae and Oleaceae, raffinose is the predominant carbohydrate translocated in the phloem.
Feb 17, 2022 · Raffinose family oligosaccharides are ubiquitous and can be directly extracted from the plant materials using water or aqueous ethanol, or methanol solutions. Raffinose is mainly extracted from sugar beets during sugar processing in Japan (Dinoto et al., 2006).
Raffinose is a trisaccharide composed of alpha-D-galactopyranose, alpha-D-glucopyranose and beta-D-fructofuranose joined in sequence by 1->6 and 1<->2 glycosidic linkages, respectively. It has a role as a plant metabolite, a Saccharomyces cerevisiae metabolite and a mouse metabolite.
Raffinose. Raffinose is a trisaccharide composed of glucose, galactose, and fructose, connected by α and β glycosidic bonds. It can be hydrolyzed to produce d-galactose and sucrose, as well as melibiose and d-fructose, through the action of specific enzymes. It is commonly found in various parts of plants and is considered a non-reducing sugar.
The so-called raffinose family of oligosaccharides comprises raffinose (trisaccharide), stachyose (tetrasaccharide), and verbascose (pentasaccharide), all of which occur in the seeds of legumes, as well as in different parts of plants.
Raffinose, a trisaccharide found in many plants, consists of melibiose (galactose and glucose) and fructose. Another plant trisaccharide is gentianose. Maltotriose, a trisaccharide of glucose, occurs in some plants and in the blood of certain arthropods.
Sep 17, 2020 · Raffinose family oligosaccharides (RFOs) are implicated in plant regulatory mechanisms of abiotic stresses tolerance and, despite their antinutritional proprieties in grain legumes, little ...
Aug 25, 2015 · RFOs are described as the most widespread D -galactose containing oligosaccharides in higher plants. Biosynthesis of RFOs begin with the activity of galactinol synthase (GolS; EC 2.4.1.123), a GT8 family glycosyltransferase that galactosylates myo -inositol to produce galactinol.
Feb 16, 2022 · Role of Raffinose Family Oligosaccharides in Human Health. Raffinose family oligosaccharides are ubiquitous in legume seeds ( Minorsky, 2003 ), and they are composed of α - (1,6)-galactosides linked to a sucrose unity ( Cardoso et al., 2021 ).
