What is glycine and why is it important?
Glycine is an amino acid that functions as a building block for certain proteins, most especially the collagen found in skin, ligaments, muscles, bones, and cartilage. Glycine is the forerunner for an array of essential metabolites, including glutathione, haem and creatine. It “acts as a neurotransmitter in the central nervous system and has many roles such as antioxidant, anti-inflammatory, cryoprotective, and immunomodulatory in peripheral and nervous tissues.” (1)
What is the glycine content in collagen?
When it comes to the presence of glycine in collagen, a large chunk of the collagen in your body is glycine. In fact, it is reported that glycine, amongst other amino acids, contributes to about “57% of total amino acids (AAs) in collagen, which accounts for one-third of proteins in humans” (2)
What is collagen and why is it important?
Collagen is the most abundant protein in our body, accounting for about one-third of its protein composition. It is vital for maintaining normal structure and strength of connective tissue, including bones, cartilage, skin, and blood vessels. Collagen "interact with cells via several receptor families and regulates their proliferation, migration, and differentiation” (3)
