Glycylglycine is the dipeptide of glycine, making it the simplest peptide. 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. The product is a biochemical reagents which is used for blood preservation and protein cytochrome C and injection of drug and stabilizer in biological research and medicine.
