It exists as a white crystalline powder that is odorless and has a slightly sweet taste. It is soluble in water but insoluble in ethanol, ether, and acetone. L - Glutamine is an important nutrient for many cells in the body, especially immune cells and cells lining the digestive tract.
This product is factory - supplied with a good price, ensuring high - quality raw materials and strict production control. It meets relevant industry standards and specifications, providing reliable quality for various applications.
1. **Medical field**:
- It is used as a nutritional supplement in clinical nutrition. For patients with malnutrition, trauma, or after surgery, L - Glutamine can help maintain the integrity of the intestinal mucosa, reduce the risk of bacterial translocation, and enhance the immune function.
- It may also play a role in the treatment of some diseases such as irritable bowel syndrome, helping to relieve symptoms and improve the function of the digestive system.
2. **Sports nutrition**:
- Athletes often use L - Glutamine supplements. During intense exercise, the body's demand for L - Glutamine increases. Supplementing it can help reduce muscle fatigue, promote muscle recovery, and improve exercise performance.
- It can also help maintain the nitrogen balance in the body, which is beneficial for muscle growth and maintenance.
3. **Cell culture**:
- In biological research and biopharmaceutical production, L - Glutamine is an essential component in cell culture media. It provides a source of nitrogen and carbon for cell growth and metabolism, promoting cell proliferation and survival.
1. **Oral use**:
- For general health maintenance, the recommended dosage is usually 5 - 10 grams per day. It can be mixed with water, juice, or other beverages and taken after meals.
- Athletes may need a higher dosage, typically 10 - 20 grams per day, depending on the intensity and duration of their training. It is often taken before or after exercise.
2. **Cell culture**:
- The concentration of L - Glutamine in cell culture media usually ranges from 2 - 4 mM. It should be added to the culture medium under sterile conditions according to the specific requirements of different cell lines.
**Case 1: Sports recovery**
A professional bodybuilder was experiencing severe muscle fatigue and slow recovery after intense training sessions. He started taking 15 grams of L - Glutamine per day. After two weeks of continuous use, he noticed a significant reduction in muscle soreness and a faster recovery rate. His strength also gradually improved, allowing him to increase the intensity of his training.
**Case 2: Clinical nutrition**
An elderly patient who had undergone abdominal surgery was suffering from poor appetite and slow wound healing. The doctor prescribed L - Glutamine supplementation at a dosage of 10 grams per day. After a month, the patient's intestinal function improved, and the wound healed faster. His immune function also strengthened, reducing the risk of postoperative infections.
**Case 3: Cell culture**
A research team was culturing a particular type of cancer cells for drug screening. They found that when they added the appropriate concentration of L - Glutamine to the culture medium, the cell growth rate increased significantly, and the cells showed better viability, which greatly facilitated their research progress.
