Dextrans: The Versatile Sugars Revolutionizing Medicine and Industry
Dextrans are branched glucose polymers synthesized by certain bacteria, primarily *Leuconostoc* and *Streptococcus* species. These sugars are biocompatible, water-soluble, and highly modifiable, making them ideal for medical and industrial uses.
2.How Do Bacteria Make Dextrans?
Certain bacteria, such as Leuconostoc mesenteroides and Streptococcus mutans, produce dextrans from sucrose using the enzyme "dextransucrase". This process breaks down sucrose into glucose and fructose, then polymerizes the glucose molecules into long, branching dextran chains.
Dextrans have diverse applications:
- Medicine:As blood volume expanders, drug delivery vehicles, and anticoagulants.
- Iron Dextran Injections: Used to treat severe iron deficiency anemia by delivering iron safely to the body.
- Food Industry: As stabilizers and thickeners in products like ice cream and sauces.
- Biotechnology: In chromatography and tissue engineering.
