Glycine is a non-essential amino acid. It is the simplest of the amino acids and plays various roles in biology. Glycine is an ACS reagent, and is used as a component of buffers for polyacrylamide gel electrophoresis and as a component of Towbin′s transfer buffer for Western blots. Glycine is structurally unique among the biological amino acids in that it does not have an asymmetric center, and thus is not chiral.
