What is the Difference Between Erythrose and Erythrulose?
🆚 Go to Comparative Table 🆚Erythrose and erythrulose are two different tetrose carbohydrates with distinct chemical and physical properties. The key differences between them are:
- Type of Carbohydrate: Erythrose is an aldose, while erythrulose is a ketose. Erythrose has an aldehyde functional group, and erythrulose has a ketone functional group.
- Number of Chiral Carbons: Erythrose has 2 chiral carbon atoms, while erythrulose has 1 chiral carbon atom.
- Biochemical Role: Erythrose is used by oxidative bacteria and has a role as a plant metabolite. In contrast, erythrulose is a tetrose carbohydrate with the chemical formula C4H8O4 and is used as a skincare ingredient for a homogenous-looking skin tone.
- Application: Erythrulose is found in some self-tanning cosmetics, combined with dihydroxyacetone (DHA), and reacts with the amino acids in the proteins of the first layers of the skin. Erythrulose produces a lighter and slower-developing tan compared to DHA-based sunless tans.
In summary, erythrose and erythrulose are different tetrose carbohydrates with distinct chemical structures, properties, and applications. Erythrose is an aldose with 2 chiral carbon atoms and a role in plant metabolism, while erythrulose is a ketose with 1 chiral carbon atom and is used as a skincare ingredient for a homogenous-looking skin tone.
Comparative Table: Erythrose vs Erythrulose
The main differences between erythrose and erythrulose are their chemical structures, properties, and uses. Here is a table comparing the two:
Property | Erythrose | Erythrulose |
---|---|---|
Chemical Structure | Aldose, with an aldehyde functional group | Ketose, with a ketone functional group |
Chiral Carbons | 2 | 1 |
Uses | Naturally occurring in plants, used by oxidative bacteria, and involved in the browning of food during preparation and storage | Useful as a skincare ingredient for a homogeneous-looking skin tone |
Erythrose is an aldose with an aldehyde functional group, while erythrulose is a ketose with a ketone functional group. Erythrose has 2 chiral carbons, whereas erythrulose has 1 chiral carbon. Erythrose is involved in various biological processes, such as being used by oxidative bacteria and playing a role as a plant metabolite. On the other hand, erythrulose is primarily used as a skincare ingredient to promote a more uniform skin tone.
