What does galactose and fructose get converted into?
In the liver, galactose is converted to glucose-6-phosphate in order to enter the glycolytic pathway. Fructose is converted into glycogen in the liver and then follows the same pathway as glycogen to enter glycolysis.
What disaccharide comprises fructose and galactose?
Common disaccharides
| Disaccharide | Unit 1 | Unit 2 |
|---|---|---|
| Sucrose (table sugar, cane sugar, beet sugar, or saccharose) | Glucose | Fructose |
| Lactose (milk sugar) | Galactose | Glucose |
| Maltose (malt sugar) | Glucose | Glucose |
| Trehalose | Glucose | Glucose |
What disaccharide does fructose make?
Sucrose
Disaccharides
| Disaccharide | Common name | Monosaccharides |
|---|---|---|
| Sucrose | Table sugar | Glucose-fructose |
| Lactose | Milk sugar | Galactose-glucose |
| Maltose | Malt sugar | Glucose-glucose |
| Isomaltose | Glucose-glucose |
What disaccharide does galactose make?
Galactose is a monosaccharide. When combined with glucose (monosaccharide), through a condensation reaction, the result is a disaccharide called lactose. The hydrolysis of lactose to glucose and galactose is catalyzed by the enzymes lactase and β-galactosidase.
Is galactose a disaccharide?
Galactose is a monosaccharide and has the same chemical formula as glucose, i.e., C6H12O6. It is similar to glucose in its structure, differing only in the position of one hydroxyl group. The major dietary source of galactose is lactose, a disaccharide formed from one molecule of glucose plus one of galactose.
Which monosaccharides make up each disaccharide?
Disaccharides form when two monosaccharides undergo a dehydration reaction (a condensation reaction); they are held together by a covalent bond. Sucrose (table sugar) is the most common disaccharide, which is composed of the monomers glucose and fructose.
What is disaccharide chemistry?
disaccharide, also called double sugar, any substance that is composed of two molecules of simple sugars (monosaccharides) linked to each other. The three major disaccharides are sucrose, lactose, and maltose.
What monosaccharides make up disaccharides?
What is fructose and galactose?
Galactose (a milk sugar) and fructose (found in fruit) are other common monosaccharides. This makes them different molecules despite sharing the same atoms in the same proportions, and they are all isomers of one another, or isomeric monosaccharides. Glucose and galactose are aldoses, and fructose is a ketose.
Is fructose a disaccharide?
Fructose is a monosaccharide found in many plants. Fructose exists in foods either as a free monosaccharide or bound to glucose as sucrose, a disaccharide.
What monosaccharides make disaccharides?
What monosaccharides make up fructose?
Commercially, fructose is derived from sugar cane, sugar beets, and maize. High-fructose corn syrup is a mixture of glucose and fructose as monosaccharides. Sucrose is a compound with one molecule of glucose covalently linked to one molecule of fructose.
Do disaccharides of galactose and fructose exist?
Disaccharides of galactose and fructose don’t seem to exist in nature, but in recent years there has been commercial production of the synthetic disaccharide galactofructose, sometimes called “Lactulose.”
What are some examples of common disaccharides?

What is formed when monosaccharides are dehydrated?
A dehydration reaction forms a disaccharide. One molecule of water is removed for each linkage formed between the monosaccharide subunits. Both natural and artificial disaccharides are known. Examples of common disaccharides include sucrose, maltose, and lactose.
What is the difference between sucrose and lactose?
Contrary to sucrose, lactose is purely animal in origin. It is only made by the lactating mammary glands of mammals. The enzyme necessary for its synthesis is only active during the phase of lactation. Lactose is the most abundant sugar found in milk and milk products like cow milk, goat milk, human milk, etc.
