Glucose can be converted into mannose through an epimerization reaction, specifically at the C2 position, which involves the enzyme mannose-6-phosphate isomerase. This process converts glucose-6-phosphate into mannose-6-phosphate, which can subsequently be dephosphorylated to yield mannose. Fructose is formed from glucose through a series of enzymatic reactions involving the conversion of glucose to glucose-6-phosphate, then to fructose-1,6-bisphosphate via phosphofructokinase, and finally to fructose through the action of aldolase. These conversions are part of the broader metabolic pathways that utilize glucose for energy production and carbohydrate metabolism.
What else can I help you with?
What suffix do most carbohydrates end in?
-ose.Such as glucose, fructose, galactose, mannose, idose, etc.-ose.
Why does Isomerase convert glucose syrup into fructose syrup?
Glucose or mannose or fructose are interconverted in presence of base. The common intermediate is the formation of an enediol, CH(OH)=CH(OH)--- , between C1 and C2. This rearrangement is also known as Lobry de-Buryn Van Ekenstein rearangement.
How do you change sucrose to glucose?
Sucrose is a disaccharide composed of glucose and fructose. A sucrase will hydrolyze sucrose into both constitute parts. You will be left with glucose and fructose, but you cannot directly transform sucrose to glucose.
What is the process for turning glucose into fructose?
Isomerisation of the glucose, which is an alpha-hydroxy-ketone, into fructose being beta-hydroxy-aldehydes.It is done together with an enzyme: glucose-isomerase and will end up in an equilibrium state when about 50% is converted in fructose (also 50%).This mixture is called:isomerose-syrup or IsoSweet(R) and is sweeter than the same amount of glucose-syrup.High Fructose Corn Steep (HFCS) liquor has up to 65% fructose by special treatment of 1.Without an enzyme the reaction could be carried out in moderate alkaline solution and then also mannose is formed.
Are glucose and fructose elements?
Yes, they have 6 carbons.
List some monosaccharides with their molecular formula?

What is a six-carbon sugar called?
A six-carbon sugar is called a hexose. Some examples of hexoses include glucose, fructose, and galactose.
Will mannose produce a positive Benedict's test?
Yes, mannose will produce a positive Benedict's test result as it is a reducing sugar. Benedict's reagent is used to detect the presence of reducing sugars such as glucose, fructose, and mannose by forming a reddish-colored precipitate when reacted with them.
What are the products of reduction of D-fructose by NaBH4?
The products of the reduction of D-fructose by NaBH4 is a 50-50 production of sorbitol and mannitol. These are the alditol forms of glucose and mannose respectively.
What suffix do most carbohydrates end in?
-ose.Such as glucose, fructose, galactose, mannose, idose, etc.-ose.

Which of these sugars are made by humans glucose fructose mannose starch vitamin c sucrose maltose lactose galactose?
Humans make glucose, fructose, and galactose, as these are monosaccharides that our bodies can produce. The others listed are not made by humans but are consumed through diet or supplementation.
How do you change sucrose to glucose?
Sucrose is a disaccharide composed of glucose and fructose. A sucrase will hydrolyze sucrose into both constitute parts. You will be left with glucose and fructose, but you cannot directly transform sucrose to glucose.
Why do you change glucose to fructose?
Glucose does not get changed to fructose. Fructose is a sugar mainly found in fruits. It is a simple sugar, like glucose, but is unusable by the body. When ingested, it is broken down by enzymes in the mouth, stomach, and intestines its carbon bonds and convert it to glucose, which is the body's main fuel.
Polysaccharides are polymers of what?
Polysaccharides are polymers of monosaccharides, which are carbohydrates. Starch and cellulose are made from glucose. Other polysaccharides are made from mannose, glacturonic acid, galactose, and fructose.

How do you make fructose?
A fructose (levulose) molecule has six carbon atoms, twelve hydrogen atoms, and six oxygen atoms which is generally found in nature, but can be produced into such sugars as high fructose corn syrup. This is done by taking corn (usually genetically modified) and milling it into corn starch. Then by adding the enzyme a-amylase followed by the enzyme glucoamylase, this turns the starch into glucose. Glucose isomerase is then added to convert the glucose into fructose. This does not convert all glucose to fructose, however. This is where the purity of the product is noted and labeled with the percentage next to HFCS (i.e. HFCS 55 signifies 55% fructose, 45% glucose).
