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.
What is raffinose?
General Information: Raffinose is a trisaccharide composed of galactose, fructose, and glucose. It can be found in beans, cabbage, brussels sprouts, broccoli, asparagus, and other plants. In plants, raffinose is generated via binding of galactinol (a sugar alcohol) to sucrose.
What foods are raffinose found in?
Raffinose — Beans contain large amounts of this complex sugar. Smaller amounts are found in cabbage, Brussels sprouts, broccoli, asparagus, other vegetables, and whole grains.
Is raffinose a reducing sugar?
As is evident from its structure (its anomeric carbon atoms are involved in glycosidic bonds), it is a non-reducing sugar.
Where does raffinose occur?
Raffinose occurs in legumes, whole grains, cabbage, brussel sprouts, broccoli, cotton seed, molasses of beet root, asparagus, etc. Raffinose is just one of the members of the RFOs (raffinose family of oligosaccharides). Other members include stachyose (a tetrasaccharide), verbascose (a pentasaccharide), etc.

Beans contain high amounts of a complex sugar called raffinose, which the body has trouble breaking down. Beans are also rich in fiber, and a high intake of fiber can increase gassiness.
Why does raffinose cause gas?
Raffinose passes through the small intestines into the large intestines where bacteria break it down, producing hydrogen, carbon dioxide, and methane gas, which exits through the rectum.

Is raffinose a complex carbohydrate?
Raffinose: A carbohydrate complex formed by binding of fructose, galactose and glucose.
Is raffinose a ketone?
Question: Raffinose is a trisaccharide composed of galactose, glucose, and fructose. It is found in broccoli, cabbage, asparagus and other vegetables, as well as in whole grains. … Fructose is a ketohexose while the other two sugars found in raffinose are aldohexoses.
What is the molar mass of raffinose?
Question: Raffinose is a trisaccharide composed of galactose, glucose, and fructose. It is found in broccoli, cabbage, asparagus and other vegetables, as well as in whole grains. … Fructose is a ketohexose while the other two sugars found in raffinose are aldohexoses.
Is raffinose a soluble fiber?
Sucrose Oligosaccharides
Raffinose oligosaccharides are a family of soluble sucrose derivatives that constitute an important form of transported carbon in some plants (e.g., pumpkin). These oligosaccharides are also stored in seeds, roots, and tubers of many plant species.
Why do I fart so much at night?
People may experience gas at night due to eating close to bedtime. Specifically, lying down very soon after eating may cause indigestion, which can produce gas. Also, eating a large meal can trigger some conditions, such as irritable bowel syndrome (IBS).
Does peanutbutter cause gas?
It gets fermented in the large intestine, which produces gas as a byproduct. The fiber content of peanut butter shouldn’t be an issue for most people in small amounts, but can cause gas if you’re eating a lot of it.
Can milk cause gas?
Milk and Milk Products
If you’re one of the many lactose-intolerant adults, dairy products can cause a significant amount of gas and bloating. People who are lactose intolerant lack the enzyme lactase, which is necessary to break down lactose (milk sugar). 4 This results in gas and bloating, among other symptoms.
How do you burp?
Get air into your throat by sucking in air through your mouth until you feel an air bubble in your throat, and then block the front of your mouth with your tongue so you can release the air slowly. This should trigger a burp.
Does gas create chest pain?
Know when it’s gas
You may feel pain in your chest if gas has gathered in your stomach or in the left portion of your colon. Gas can become trapped in your digestive tract when you swallow too much air. There are other food-related reasons why you may feel gas pain near your chest.
Which beans make you fart the most?
According to several articles, soybeans are the fartiest and also contain the highest percentage of sugars. Navy beans and pinto beans are the next top offenders. And other worthy contestants include black beans, lima beans, black-eyed peas, and chickpeas.
Is lactose a disaccharide?
The three major disaccharides are sucrose, lactose, and maltose. Sucrose, which is formed following photosynthesis in green plants, consists of one molecule of glucose and one of fructose bonded via an α-,β-linkage.

Where do lactose molecules come from?
lactose, carbohydrate containing one molecule of glucose and one of galactose linked together. Composing about 2 to 8 percent of the milk of all mammals, lactose is sometimes called milk sugar. It is the only common sugar of animal origin. Lactose can be prepared from whey, a by-product of the cheese-making process.
Which does not show Muta rotation?
Sucrose does not exhibit mutarotation because the glycosidic bond is between the anomeric carbon of glucose and anomeric carbon of fructose.
Which of the following disaccharide do not Mutarotate?
Glucose is also a reducing sugar show mutarotation. We can conclude that the Sucrose is not a reducing sugar because it does not have a hydroxyl group in the ring. Hence, sucrose does not show mutarotation.
Which can show mutarotation?
Glucose, fructose, maltose as well as galactose all have a free hydroxyl group and thus are known as reducing sugars. Hence, all of these will undergo mutarotation.
Are raffinose and stachyose examples of polysaccharides?
Complex Carbohydrates
Examples are raffinose and stachyose. Polysaccharides are often made up of a large number of monosaccharides and disaccharides. Examples are starch, glycogen and cellulose.
What kind of glycosidic bond connect sugars in raffinose?
Raffinose is a trisaccharide in which glucose acts as a monosaccharide bridge between galactose and fructose. It has both α and β glycosidic bonds and can therefore be hydrolyzed to d-galactose and sucrose via enzymes with α-glycosidic activity, and to melibiose and d-fructose via enzymes with β-glycosidic activity.
