Glycine
Aliphatic (non-polar) Most simple, optically inactiveHydrogen for R
Glycine is a non-essential amino acid that is integral to protein synthesis and important for various physiological functions in the human body. It is the simplest amino acid, with just a single hydrogen atom as its side chain. Glycine is a non-polar and neutral amino acid and its chemical formula is NH2CH2COOH.
Functions of Glycine:
1. Protein synthesis: The amino acid glycine is incorporated into the polypeptide chains during protein synthesis.
2. Neurotransmitter: Glycine acts as a neurotransmitter in the central nervous system inhibiting nerve impulses in the spinal cord and brainstem.
3. Glutathione production: Glycine plays a key role in the production of glutathione, a powerful antioxidant important for the proper functioning of the immune system and detoxification processes in the body.
4. Wound healing: Glycine has shown to enhance the process of wound healing. It stimulates the proliferation of fibroblasts, making up the connective tissue and enhances the formation of collagen.
5. Digestive health: Glycine plays a crucial role in maintaining digestive health. It is involved in the synthesis of bile salts, which are necessary for the breakdown and absorption of fats in the digestive system.
Sources of Glycine:
Glycine is found in high quantities in protein-rich foods like meat, fish, beans, and dairy products. It is also used in dietary supplements for sports nutrition due to its many health benefits. Additionally, the body can synthesize glycine from other amino acids, so it is considered a non-essential amino acid.
