Arginylglycylaspartic acid (RGD) is a tripeptide composed of L-arginine, glycine, and L-aspartic acid. The sequence is a common element in cellular recognition.[1] Arginylglycylaspartic acid is used as a biochemical tool in the study of this recognition.

RGD-peptides are implicated in cellular attachment via integrins, and can be used to coat synthetic scaffolds in tissue engineering to enhance cellular attachment by mimicking in vivo conditions.[2]
