This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
In woody plants, cucurbits, and legumes, stachyose is known to play a significant role in both the storage and transport of sugar.
What is the function of stachyose?
Stachyose has an average sweetness level that is approximately 28% lower than that of sucrose. Its primary application is either as a sweetener in bulk or for the functional oligosaccharide qualities it possesses. Stachyose is only partially digested by humans and has a caloric value ranging from 1.5 to 2.4 kcal per gram (or 6 to 10 kJ per gram).
Is stachyose a sugar that has a lowering effect?
Stachyose is a type of sugar that does not reduce. Sugar that is not reducing has no effect on the reduction of Fehling’s solution or Tollen’s reagent.
What kinds of foods have stachyose in them?
Stachyose, along with other similar oligosaccharides like raffinose, can be found naturally in a wide variety of vegetables (including green beans, soybeans, and other types of beans), as well as other types of plants.
Where do raffinose and stachyose diverge from one another?
Raffinose contains one galactose moiety linked to sucrose through an -1,4 bond, whereas stachyose, verbascose, and ajugose each contain two, three, or four galactose moieties, respectively.
What exactly does it mean when someone uses the word STACHYOSE?

Can humans digest stachyose?
carbohydrates. , 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.
Does raffinose result in a decrease in sugar?
Raffinose is a trisaccharide that is found in sugar beets, however it plays just a supporting role there. (a) This is not a sugar that reduces. There is no possibility of open-chain formations.
What constituents does a Stachyose have?
A tetrasaccharide known as stachyose is made up of sucrose that has an alpha-D-galactosyl-(1->6)-alpha-D-galactosyl moiety bonded to it at the 6-position of the glucose molecule. It has a purpose both as a metabolite in plants and as a metabolite in mice…. It originates from a combination of sucrose and raffinose.
Is Stachyose the same thing as sugar?
In woody plants, cucurbits, and legumes, stachyose is known to play a significant role in both the storage and transport of sugar.
Which enzyme is responsible for the breakdown of stachyose?
Beans, cabbage, brussels sprouts, broccoli, asparagus, as well as other vegetables and whole grains, are all good sources of this nutrient. The enzyme known as -galactosidase (-GAL), which is not present in the digestive system of humans, is necessary for the hydrolysis of raffinose into D-galactose and sucrose.
Which type of carbohydrate occurs the most frequently in the natural world?
Cellulose is the most prevalent form of the carbohydrate that may be found in nature.
Which of these forms of carbohydrates is the most basic?
Monosaccharides. Monosaccharides are the simplest form of carbohydrates since they cannot be broken down any further by the body. With the exception of fructose, this makes it possible for them to be swiftly and easily absorbed by your body. There are three categories of monosaccharides, which are as follows (1):
Is sucrose capable of lowering sugar levels?
4.4 Inorganic Chemistry
Because sucrose is a non-reducing sugar, it must first be hydrolyzed into its components, glucose and fructose, before it can be detected using this assay. This can be done by adding a little amount of acid to the mixture.
Can stachyose be considered a prebiotic?
A functional oligosaccharide known as stachyose tetrahydrate performs the role of a prebiotic in the body. Stachyose tetrahydrate may inhibit the growth of colon cancer cells in a roundabout way. It does this by stimulating the growth of probiotics or the production of other advantageous substances in the intestine.
What is the definition of an oligosaccharide?
2.2 Oligosaccharides. Oligosaccharides are a type of carbohydrate that can include anywhere from 2-10 monosaccharide units in their structure… Those oligosaccharides with two monosaccharide residues, which are more widely known as disaccharides, make up the majority of the molecule’s total mass. They comprise glucose, maltose, lactose, and trehalose in addition to cellobiose and sucrose.
What exactly is the nature of the glycosidic bond found in stachyose?
A galactose is added to the existing 6-1 glycosidic link in a raffinose molecule, which results in the formation of stachyose, one of the most significant four sugars found in nature. In a similar fashion, the, D-galactose can be joined to a glycosidic bond in order to generate pentasaccharide, hexasaccharide, and seven sugar homologues.
What exactly are sugars that are reduced?
A sugar is said to be reducing if it can reduce another chemical while also being oxidized itself. This means that the carbonyl carbon of the sugar can be converted into a carboxyl group. A sugar is only considered to be in the category of reducing sugars if it possesses an open-chain form and either an aldehyde group or a free hemiacetal group.
Is stachyose considered to be a complex sugar?
Oligosaccharides and polysaccharides are two different types of carbohydrates that are found inside complex carbohydrates. Oligosaccharides, which get their name from the word “few,” are made up of anything from 3 to 10 sugar units, while polysaccharides include more than 10 sugar units. Oligosaccharides most frequently encountered are raffinose and stachyose.
Is sucrose considered to be a white sugar?
Sucrose is a form of white sugar that has been crystallized. It is derived from the sugar cane plant and is used in cooking and baking around the world. Sucrose is a disaccharide that is rapidly broken down into its component parts and is composed of glucose and fructose in an equal and equal proportion.
Which items fall under the category of tetrasaccharides?
Carbohydrates can be classified as tetrasaccharides if their breakdown results in the release of four molecules of the same or separate monosaccharides. By way of illustration, the hydrolysis of stachyose results in the production of one molecule each of glucose and fructose in addition to two molecules of galactose. Generally speaking, the chemical formula for a tetrasaccharide is written as C24H42O21.
Raffinose is a type of saccharide. What kind is it?
Raffinose is a trisaccharide, which means that it is composed of three monomers of monosaccharides, specifically galactose, glucose, and fructose. Raffinose is derived by petroleum distillation. It can be represented by the chemical formula C18H32O16. With a glycosidic connection that is 1 to 6, the galactose is attached to the glucose.
Is maltose a sugar?
Maltose is a type of sugar that is produced by linking together two glucose molecules. It is produced in the seeds of plants as well as in other areas of the plant as the plant attempts to break down its stored energy so that it can sprout.
Is maltose decreasing sugar?
Maltose is considered to be a reducing sugar since the free aldehyde that is produced when the ring is opened might react with Fehling’s solution.
Can you give some examples of sugars that do not reduce?
- Sucrose.
- Trehalose.
- Raffinose.
- Stachyose.
- Verbascose.
Are oligosaccharides decreasing sugars?
Oligosaccharides are chains consisting of a small number of monosaccharides connected to one another by glycosidic linkages. The prefix “oligo-” literally means “few.” A mono- or oligosaccharide that has either a hemiacetal or a hemiketal group attached to it is considered to be a reducing sugar. All of the sugars listed above that are monosaccharides are reducing sugars, whereas all of the sugars listed above that are polysaccharides are non-reducing.
