Within the expanding landscape of short-chain bioactive peptides, copper-binding motifs occupy a particularly intriguing niche. Among these, glycyl-L-histidyl-L-lysine complexed with copper (GHK-Cu) has attracted sustained attention for its compact structure and broad biochemical relevance. Originally identified in plasma as a naturally occurring tripeptide with affinity for copper ions, GHK-Cu has since been positioned as a …The post GHK-Cu: Metal Signaling, Matrix Dynamics, and Regenerative Inquiry appeared first on Chandigarh Metro.
