Usage Examples for "Ornithine"
1. Scientific Context
In biochemistry, ornithine is a non-proteinogenic amino acid that is involved in the urea cycle, which helps remove excess ammonia from the body. The enzyme ornithine transcarbamylase (OTC) is essential for converting ornithine into citrulline.
2. Medical Research
Researchers at the University of California, San Francisco, have discovered that ornithine supplementation can help reduce symptoms of bipolar disorder in patients. The study found that ornithine increased the levels of a neurotransmitter called GABA, which helps regulate mood.
3. Sports Nutrition
Ornithine alpha-ketoglutarate (OKG) is a natural dietary supplement that has been show to increase muscle protein synthesis and reduce muscle soreness in athletes. A study published in the Journal of Strength and Conditioning Research found that OKG supplementation improved muscle recovery after exercise.
4. Nutritional Supplements
Ornithine is often used as an ingredient in nutritional supplements that support muscle growth and recovery. It can be found in various forms, including capsules, tablets, and powders.
5. Compound Structure
The molecular structure of ornithine consists of a 5-carbon amino acid chain with an amino group (-NH2) and a carboxyl group (-COOH). Its chemical formula is C5H11NO3.
