Physical properties of glycine:

• Glycine is a colorless compound with a sweet taste. 
• Its molecular weight is 75.066 grams per mole and density is 1.161g/cm3. 
• It starts to decompose at temperatures equal to or around 233℃. This makes it difficult to determine glycine’s melting point, which remains unknown to date. 
• Glycine is highly soluble in water. 

Chemical properties of glycine: 

• Glycine is nonpolar. It acts as a buffer solution at a pH of 6.   
• Glycine is hydrophilic because of its one hydrogen atom side chain.
• It can be synthesized from amino acids such as serine and threonine as well as a few other sources.
