raf·fi·nose

(raf'i-nōs),
A dextrorotatory trisaccharide, occurring in cotton seed and in the molasses of beet root, composed of d-galactose, d-glucose, and d-fructose and formed by transfer of d-galactose from UDP-d-galactose to sucrose; many seeds are rich in raffinose.

raffinose

(răf′ə-nōs′)
n.
A trisaccharide, C18H32O16, composed of glucose, fructose, and galactose. It is obtained from sugar beets and cottonseed meal and is present in many legumes.

raffinose

(răf′ĭ-nōs)
A trisaccharide, melitose, present in certain plants, cereals, and fungi. Hydrolysis yields fructose and melibiose.

Additionally, we examined the recruitment of Med6p mutants to an endogenous GAL1-10 promoter region under either repression (glucose) or induction conditions (galactose plus raffinose) to monitor the effect of med6 mutations on the recruitment of Mediator to a natural promoter.

The results can be attributed to the presence of the raffinose oligosaccharides.
While high oleic and low linolenic acid content are of importance to the commodity soybean, the manipulation of raffinose family oligosaccharides (RFOs) is also an important aspect to improving soybean seed components [15].
Galactinol and myoinositol, two precursors of raffinose, showed contrasting patterns in tobacco roots.
Carbohydrate fermentation was tested on MRS supplemented with bromocresol purple as a pH indicator using the following sugars to differentiate the subspecies of Leuconostocs: Arabinose, Glucose, galactose, lactose, fructose, sucrose, sorbitol, mannitol, maltose Rhamnose, Raffinose, xylose [25, 26].
During observations, 39 specimens were growth positive; the biochemistry of isolates revealed that they were coagulase, catalase and oxidase negative, TSI, gel hydrolysis positive and were able to ferment glucose, lactose, maltose, galactose, fructose, sucrose, starch and raffinose. The results of antimicrobial activity showed that pneumococci were resistant to the cefspan, septran, cravit, pipemetic acid, azomax, bacitracin, and penicillin and a clear zone of inhibition was observed on clithromycin, optochin, cefizox, genatamycin, minocyclin, levoflaxacin, and vancomycin.
The main oligosaccharides in soy milk are raffinose and stachyose, while the major disaccharide is sucrose [33].
Besides carbon transport, sucrose can act at the final stage of seed formation as a substance reserve, to be used for the germination process, and serve as the basis for the synthesis of raffinose sugar series, that confer increased tolerance to desiccation, contributing to the maintenance of seed quality (BUCKERIDGE et al., 2004).
