glycyl-glycine

Glycylglycine (Diglycine) is a dipeptide used in biochemical research. It is the simplest of all dipeptides and is used as a starting template for preparation of more complex peptides. Glycine is involved in the body's production of DNA, phospholipids, and collagen, and in the release of energy.

Glycylsarcosine (GLYCYL-SARCOSINE) is a dipeptide obtained by formal condensation of the carboxy group of glycine with the amino group of sarcosine

H-Gly-Pro-OH (Glycyl proline) is a dipeptide composed of glycine and proline, and is an end product of collagen metabolism

Glycyl-L-valine, a dipeptide composed of glycine and valine, is an incomplete breakdown product of protein digestion or protein catabolism (incomplete breakdown product of protein digestion or protein catabolism).

H-Gly-Gly-Pro-OH (Glycyl-glycyl-L-proline) is a dipeptide composed of glycine and proline, and is an end product of collagen metabolism that is further cleaved by prolidase.
