Henri Braconnot discovered Glycine in 1820 that became the first instance in which a pure amino acid was received from a protein (gelatin) by acidic hydrolysis.

This amino acid is the first of all necessary ones for a healthy digestive system, because it helps regulate the synthesis of the bile acid utilized to help you digest fats. Glycine also plays a role as an inhibitory neurotransmitter in your central nervous system, particularly in the spinal cord, in the brainstem, and in the retina. This amino acid is essential for the development and quality of human skeletal muscles, tissues, and structural integrity, as well as for the synthesis of nucleic acids.
Glycine is a non-essential amino acid, implying that our bodies are able to produce it. Like many other amino acids, this one is used to help create muscle tissues and convert glucose into energy. In addition, it is also vital for maintaining healthy central nervous and digestive systems. The latest researches showed that it can also provide protection against some types of cancer through antioxidants.
Glycine is utilized in human body to help construct normal DNA and RNA strands, which are basically a genetic material necessary for proper cellular function and formation. This amino acid helps prevent the breakdown of muscles, because it can boost your body's levels of creatine - a compound helping build muscle mass. Aside from the muscles, high concentrations of this amino acid are also found in the skin and other connective tissues. For example, nearly one third of a collagen, which is responsible for keeping the skin and connective tissues firm and flexible, consists of Glycine. In other words, without this amino acid your body would not be able to repair damaged tissues.
Another benefit of Glycine is that it is essential for the central nervous system functioning. According to some researches, it is able to help inhibit the neurotransmitters causing seizure activity, hyperactivity, as well as manic (bipolar) depression. Moreover, Glycine can be converted to another neurotransmitter to help manage schizophrenia. You can find Glycine in various high-protein foods like beans, fish, meat, milk, and cheese.
