Application of Glycylglycine:

Glycylglycine is the dipeptide of glycine, making it the simplest peptide.The compound was first synthesized by Emil Fischer and Ernest Fourneau in 1901 by boiling 2,5-diketopiperazine (glycine anhydride) with hydrochloric acid. Shaking with alkali and other synthesis methods have been reported.
Because of its low toxicity, it is useful as a buffer for biological systems with effective ranges between pH 2.5-3.8 and 7.5-8.9, however, it is only moderately stable for storage once dissolved.It is used in the synthesis of more complex peptides.
