Ketose
(Redirected from Ketoses)
A type of monosaccharide containing a ketone group
Ketose is a type of monosaccharide (simple sugar) that contains a ketone group. Ketoses are important in various biological processes and are found in many natural sources. Unlike aldoses, which contain an aldehyde group, ketoses have a carbonyl group (C=O) located at the second carbon atom of the sugar chain.
Structure[edit | edit source]
Ketoses are characterized by the presence of a ketone group, which is a carbon atom double-bonded to an oxygen atom (C=O). This group is typically located at the second carbon atom in the sugar chain, distinguishing ketoses from aldoses, where the carbonyl group is at the terminal carbon.
Common Ketoses[edit | edit source]
Some common ketoses include:
- Dihydroxyacetone - The simplest ketose, with the chemical formula C_H_O_. It is a triose, meaning it contains three carbon atoms.
- Fructose - A hexose sugar with the formula C_H__O_, commonly found in fruits and honey. It is one of the most important ketoses in human metabolism.
- Ribulose - A pentose sugar with the formula C_H__O_, involved in the Calvin cycle of photosynthesis.
Biological Importance[edit | edit source]
Ketoses play crucial roles in various metabolic pathways. For example, fructose is a key player in the glycolysis pathway, where it is phosphorylated and converted into intermediates that enter the energy-producing cycles of the cell.
Metabolism[edit | edit source]
In the human body, ketoses are metabolized through pathways such as glycolysis and the pentose phosphate pathway. Fructose, for instance, is converted into fructose-1-phosphate by the enzyme fructokinase, and then further processed into intermediates that can be used for energy production or biosynthesis.
Sources[edit | edit source]
Ketoses are naturally found in various foods. Fructose, for example, is abundant in fruits, vegetables, and honey. It is also a component of sucrose, a disaccharide composed of glucose and fructose.
Chemical Properties[edit | edit source]
Ketoses can undergo isomerization to form aldoses through a process called tautomerization. This isomerization is facilitated by the presence of an enediol intermediate, allowing the conversion between the ketone and aldehyde forms.
