Glycine is the simplest amino acid, with the chemical formula NH₂CH₂COOH. It appears as a white crystalline solid that is sweet-tasting and soluble in water.
🏭⚗️ Production
Glycine is commercially produced by chemical synthesis methods, including the Strecker synthesis and from chloroacetic acid via ammonia substitution.
🔬 Properties
• White crystalline powder with a melting point around 233 °C (decomposes).
• Amphoteric in nature, meaning it can act as both an acid and a base.
• Highly soluble in water and forms zwitterions in neutral solutions.
🧪 Applications
• Pharmaceuticals & Nutrition: Used as a dietary supplement and in intravenous feeding formulations.
• Food Industry: Serves as a sweetener and flavor enhancer.
• Industrial: Used in the manufacture of herbicides, plastics, and cosmetics.
• Biochemical Research: Acts as a buffering agent in biochemical and molecular biology experiments.
