Amino Acid: Glycine
29 Jun 2023FixingChickenhealth
Glycine is the simplest amino acid in terms of its structure, as it consists of just a hydrogen atom as its side chain. It is a non-essential amino acid, meaning that the body can synthesize it on its own. However, it is also obtained from dietary sources and plays several important roles in the body:
- Protein building block: Glycine is one of the 20 amino acids used by the body to build proteins. It serves as a constituent of many important proteins and enzymes.
- Collagen synthesis: Glycine is a crucial component of collagen, the most abundant protein in the human body. Collagen provides structural support to various tissues, including skin, bones, tendons, ligaments, and blood vessels. Glycine contributes to the triple helix structure of collagen and helps maintain its stability.
- Neurotransmitter: Glycine acts as an inhibitory neurotransmitter in the central nervous system. It can bind to specific receptors in the brain and spinal cord, playing a role in regulating nerve signals and promoting relaxation.
- Detoxification: Glycine is involved in various detoxification processes in the body. It participates in the synthesis of glutathione, a powerful antioxidant that helps protect cells from oxidative damage and assists in the elimination of toxins.
- Energy production: Glycine is involved in the synthesis of creatine, a compound that plays a role in energy production and muscle function. Creatine helps provide energy for high-intensity activities and is particularly important for athletes and those engaged in intense physical exercise.
Glycine receptors: Glycine receptors are present in the spinal cord and brainstem, where they play a role in regulating neuronal activity and motor control.
In terms of dietary sources, glycine is found in various protein-rich foods, including meat (especially pork and chicken), fish, seafood, dairy products, legumes, and gelatin. It is also available as a dietary supplement.
