Glycine is an amino acid that the human body is able to produce on its own, unless it receives the necessary amount from food.In the liver, this amino acid is produced from serine and threonine, but glycine itself serves as a raw material for purine bases: guanine, adenine, xanthine, and natural porphyrin pigments.
This sweet-tasting amino acid was first introduced in 1820 from gelatin. In large quantities it is also represented in silk fibers. In the body it is concentrated in muscles, skin and connective tissue.Glycine is the smallest amino acid in size and the only one that does not have stereoisomers, but it plays an important role for the body, participates in many biochemical processes, and is also one of the 20 amino acids that form proteins.
Glycine is found mainly in foods of animal origin, including meat, fish, poultry and dairy foods. Also, the body can receive additional portions of amino acids from various kinds of dietary supplements. Given that a person is able to independently produce glycine, the substance has extremely low toxicity, and its excess is excreted in the urine.
This acid is actively used to treat schizophrenia, stroke, benign prostatic hyperplasia, genetic metabolic disorders. And considering the beneficial effect on the work of the nervous system, this substance is prescribed to sufferers with insomnia, and also used to suppress drug addicts at the first stages of treatment.
Also this amino acid is extremely important for the proper functioning of the kidneys. In particular, it protects against side effects of certain medications used after organ transplantation. The positive effect of amino acid is felt on the liver, especially in people who abuse alcohol. It is used for healing ulcers in different areas of the skin, as well as for improving memory.
The formation of healthy muscle tissue and the conversion of glucose into energy are important tasks of glycine. Also, this substance is important for maintaining the health of the central nervous and digestive systems. As the research results show, in tandem with antioxidants it protects against some types of cancer.
Glycine is an important component for the construction of DNA and RNA strands, and they, in turn, are a genetic building material, without which the correct functioning of the body is impossible. This is one of the three amino acids that make up creatine,necessary for the growth of muscle tissue and energy production under physical stress.
Also, this amino acid is part of the collagen responsible for the normal condition of the skin, ligaments and tendons. By the way, almost a third of the collagen, which provides the skin with plasticity and elasticity, consists of glycine. It promotes the absorption of calcium, which prevents the degeneration of muscles and also plays an important role in the process of producing hormones responsible for the performance of the immune system.
