Glycine

Glycine is a non-essential amino acid that plays a crucial role in many physiological processes in the body. It is the simplest of all amino acids and is the only amino acid that is not chiral, meaning it does not have a left or right-handed form. Glycine is involved in the production of DNA, RNA, and various proteins in the body. It is also a neurotransmitter and has been found to have a calming effect on the brain, leading to its use as a dietary supplement for sleep and relaxation. In addition, glycine is a precursor for the synthesis of other important molecules in the body, such as creatine, heme, and glutathione. It can be obtained from dietary sources such as meat, fish, dairy products, and legumes, or can be synthesized by the body from other amino acids.
