Glutamine, scientific name 2-amino-4-formamide butyric acid, English Glutamine(Gln). It's an amide of glutamate. L-glutamine is a coding amino acid in protein synthesis, which is non-essential for mammals and can be converted from glucose in the body
L-glutamine, the product used in food processing as a nutritional supplement, aroma enhancer. And L glutamine is an important nutritional supplement for bodybuilding sports and bodybuilders. It (hereinafter called glutamine) is the most abundant free amino acid in muscle, accounting for about 60% of the total free amino acid in the human body. Fasting plasma glutamine concentration was 500-750umol/L. Glutamine is not an essential amino acid; it is synthesized in the body from glutamic acid, valine, and isoleucine. Under stress conditions such as disease, poor nutritional status or high intensity exercise, the body's demand for glutamine increases
