What is stachyose found in?
Stachyose is a normal human metabolite present in human milk and is naturally found in many vegetables (e.g. green beans, soybeans and other beans) and plants.
What foods contain raffinose stachyose?
, raffinose and stachyose), which contains three to 10 saccharide units; these compounds, which are found in beans and other legumes and cannot be digested well by humans, account for the gas-producing effects of these foods.
What enzyme breaks down stachyose?
α-galactosidase
The young leaves contain a unique alkaline α-galactosidase which efficiently hydrolyzes stachyose and raffinose for further metabolism.
Is stachyose a dietary fiber?
The dietary fiber components included insoluble and soluble dietary fibers as well as the antinutritional raffinose family of oligosaccharides (RFOs; raffinose, stachyose, and verbascose).
Is cabbage an oligosaccharide?
Oligosaccharides (oligo means few) are composed of 3-10 sugar units and polysaccharides contain greater than 10 sugar units. Raffinose and stachyose are the most common oligosaccharides. They are found in legumes, onions, broccoli, cabbage, and whole wheat1.
Can humans break down stachyose?
Stachyose is less sweet than sucrose, at about 28% on a weight basis. It is mainly used as a bulk sweetener or for its functional oligosaccharide properties. Stachyose is not completely digestible by humans and delivers 1.5 to 2.4 kcal/g (6 to 10 kJ/g).
What enzyme digests raffinose?
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.
Which type of fiber is good for constipation?
Foods that are good sources of soluble fiber include apples, bananas, barley, oats, and beans. Insoluble fiber helps speed up the transit of food in the digestive tract and helps prevent constipation. Good sources of insoluble fiber include whole grains, most vegetables, wheat bran, and legumes.
Which is a poor source of dietary fiber?
The typical salad vegetables like lettuce and cucumber are generally poor sources of fiber, but root vegetables and beans are rich in this nutrient. Celery, cherries, and fruit juices, except tomato juice, are also poor sources of fiber. Dairy products and animal foods have no fiber.
What is difference between raffinose and stachyose?
Raffinose has one galactose moiety linked to sucrose through an α-1,4 bond, while stachyose has two, verbascose three, and ajugose four.
Where is stachyose found in a woody plant?
Stachyose is recognized as a major storage and transport sugar in woody plants, cucurbits and legumes. The kinetics of l4 C labeling of oligosaccharides during photosynthetic fixation of l4 CO z in leaves of Catalpa and Buddleia demonstrated that stachyose is synthesized at the expense of the pool of raffinose and galactinol.
What are the sugars in raffinose and stachyose?
Raffinose, stachyose and verbascose may promote the growth of beneficial intestinal bacteria, but are currently not considered prebiotics. Raffinose, also called melitose, is composed of 3 sugars : galactose, glucose and fructose [1].
How does raffinose, stachyose, verbascose work in the intestine?
In the large intestine, raffinose, stachyose and verbascose act as a soluble dietary fiber, which means they can make stools softer [66]. Raffinose, stachyose and verbascose may promote the growth of beneficial intestinal bacteria, but are currently not considered prebiotics.
What makes up the oligosaccharide family raffinose family?
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.
