Glutamine - Benefits, Deficiency Symptoms And Food Sources
What is Glutamine ?
Glutamine is a non-essential amino acid. It is the most abundant free amino acid found in the muscles of the body. Because it can readily pass the blood-brain barrier, it is known as brain fuel. In the brain, glutamine is converted into glutamic acid -which is essential for cerebral function and vice versa. It also increases the amount of GABA, which is needed to sustain proper brain function and mental activity. It assists in maintaining the proper acid/alkaline balance in the body, and is the basis of the building blocks for the synthesis of RNA and DNA.
It promotes mental ability and the maintenance of a healthy digestive tract. Glutamine serves as a source of fuel for cells lining the intestines and it is also used by white blood cells and is important for immune function.
When an amino acid is broken down, nitrogen is released. The body needs nitrogen, but free nitrogen can form ammonia, which is especially toxic to brain tissues. The liver can convert nitrogen into urea, which is excreted in the urine, or nitrogen may attach itself to glutamic acid. This process forms glutamine. Glutamine is unique among the amino acids in that each molecule contains not one nitrogen atom but two. Thus, its creation helps to clear ammonia from the tissues, especially brain tissue, and it can transfer nitrogen from one place to another
Uses and Benefits of Glutamine
Glutamine is found in large amounts in the muscles and is readily available when needed for the synthesis of skeletal muscle proteins. Because this amino acid helps to build and maintain muscle, supplemental glutamine is useful for dieters and bodybuilders. More important, it helps to prevent the kind of muscle wasting that can accompany prolonged bed rest or diseases such as cancer and AIDS. This is because stress and injury (including surgical trauma) cause the muscles to release glutamine into the bloodstream. In fact, during times of stress, as much as one third of the glutamine present in the muscles may be released. As a result, stress or illness can lead to the loss of skeletal muscle. If enough glutamine is available, however, this can be prevented.
Supplemental L-glutamine can be helpful in the treatment of arthritis, autoimmune diseases, fibrosis, intestinal disorders, peptic ulcers, connective tissue diseases such as polymyositis and scleroderma, and tissue damage due to radiation treatment for cancer. L-glutamine can enhance mental functioning and has been used to treat a range of problems, including developmental disabilities, epilepsy, fatigue, impotence, depression, schizophrenia, and senility. It preserves glutathione in the liver and protects that organ from the effects of acetaminophen overdose. It enhances antioxidant protection. L-glutamine decreases sugar cravings and the desire for alcohol, and is useful for recovering alcoholics.
Many plant and animal substances contain glutamine, but it is easily destroyed by cooking. If eaten raw, spinach and parsley are good sources. Supplemental glutamine must be kept absolutely dry or the powder will degrade into ammonia and pyroglutamic acid. Glutamine should not be taken by persons with cirrhosis of the liver, kidney problems, Reye's syndrome, or any type of disorder that can result in an accumulation of ammonia in the blood. For such individuals, taking supplemental glutamine may only cause further damage to the body. Be aware that although the names sound similar, glutamine, glutamic acid (also sometimes called glutamate), glutathione, gluten, and monosodium glutamate are all different substances.
Deficiency Symptoms of Glutamine
Deficiency Symptoms of Glutamine is rare, since it can be manufactured by the body but some are :-
Recommended Dosage of Glutamine
The minimum Recommended Dosage Allowance of Glutamine is from 500 to 1000 mg. as per requirement of the body.
Rich Food Sources of Glutamine
Glutamine is found in many high protein foods, such as fish, meat, beans, and dairy as well as in vegetables such as raw parsley and spinach.
People suffering from liver or kidney problems do not take Glutamine.
