Triose[edit | edit source]
A triose is a type of monosaccharide that contains three carbon atoms. The general chemical formula for a triose is C_H_O_. Trioses are the simplest form of carbohydrates and play a crucial role in metabolism.
Types of Trioses[edit | edit source]
There are two main types of trioses, which are classified based on the functional group present:
- Aldotriose: This type of triose contains an aldehyde group. The most common aldotriose is glyceraldehyde.
- Ketotriose: This type of triose contains a ketone group. The most common ketotriose is dihydroxyacetone.
Structure[edit | edit source]
Trioses have a simple structure with three carbon atoms. In the case of glyceraldehyde, the structure is:
- CH_OH-CHOH-CHO
For dihydroxyacetone, the structure is:
- CH_OH-CO-CH_OH
Role in Metabolism[edit | edit source]
Trioses are important intermediates in several metabolic pathways. They are involved in:
- Glycolysis: During glycolysis, glucose is broken down into two molecules of glyceraldehyde-3-phosphate, a triose phosphate.
- Calvin Cycle: In the Calvin cycle, glyceraldehyde-3-phosphate is one of the products of the light-independent reactions in photosynthesis.
