Glycine is widely used in the food industry as a flavor enhancer and sweetener, often added to beverages, protein supplements, and processed foods to improve taste. In pharmaceuticals, it serves as a buffering agent in antacids, analgesics, and intravenous medications, helping to stabilize pH levels. It is also a key component in skincare products, where it acts as a humectant to retain moisture and improve skin texture. Additionally, glycine is utilized in animal feed to promote growth and enhance nutrient absorption. In biochemical research, it is a common ingredient in buffer solutions and cell culture media, supporting protein synthesis and cell growth. Its role as a neurotransmitter inhibitor in the central nervous system makes it valuable in studies related to neurological disorders.
